Especially and most impressively Lucky Luke. A D who nails A and B perfectly.
To great comedic effect. His most famous trick is of course shooting his own shadow before it can draw. In the latest movie Tous a l'Ouest his shadow is visibly angry at being beaten to the punch once again.
Another animated example (from the 80s series) where recurring villain Joe Dalton throws a few coins in the air and shoots each of them to impress Lucky Luke, to which the cowboy replies by throwing a dollar bill in the air and shooting it...causing a hail of small change to fall on Joe's head.
In one of his first encounters with Billy the Kid, Billy tries to show off his speed by dropping a piece of candy and drawing his gun before it touches the ground. Lucky Luke then drops another piece, draws his gun, holsters it again, then catches the candy and eats it. Billy is visibly upset. It was his candy, too.
Anime and Manga
Train Heartnet from Black Cat combines elements from A, C, and D. He also practices Gun Kata.
Genjyo Sanzo from Saiyuki is definitely A, being able to shoot a seed implanted next to Gojyo's heart by Chin Yiso without hitting the heart. In Reload, he also managed to hit Ukoku with a pistol 3 times the size of his weapon of choice...which he had never fired before, not even once...while suffering from multiple broken bones.
Said pistol had belonged to another Gunslinger in the series, Gatto Nenehawk, who was a type B and used HUGE twin pistols.
Spike Spiegel borrows elements from C and D. Mad Pierrot is a type B.
Noir; Kirika has a near-mystical gift for firearms, accurately shooting without looking or while performing leaps, rarely if ever missing; she is explicitly type "A". As one fan review put it, "Kirika isn't a ninja, she's a witch."
She's also a C, at least by Noir-standards.
The title character of Madlax also fits under A, though she ventures into Gun Kata territory (and thus C) during the final episodes.
Arguably, Alucard fights with all three types of improbable gun tactic, as he has pulled a few trick shots in his time (including one in the first episode). However, none of that matters when you have enough power to kill gods and demons in horrible, horrible ways with little to no effort after seemingly being torn apart by their best attack.
Alucard is kind of unique in that he's one of the few gunslingers who has other ways (namely vampiric superstrength/speed, shapeshifting, and the hellhounds) to take out his enemies. He doesn't really have to use guns... but he sure does like to!
Samurai Gun, naturally, makes heavy use of this trope in its Steam Punk Historical Japan setting. The main character, Ichimatsu, and by extent the other Samurai Guns, are a combination of Types A and C. Type Bs show up in several episodes of the anime, including a minigun-toting Implacable Man who is only fighting because it's the only way to keep up the supply of medicine he needs to keep his sick mother alive. The main member of the Anti-Samurai Gun Unit (in the anime, at least) is actually a blend of Types B through D; his primary weapon is a Steam Punk Uzi, but he has the same bullet-dodging training as a Samurai Gun and once proves accurate enough to shoot his opponent's bullet out of the air.
Vash from Trigun embodies A, C, and D, as he tries to avoid gunplay whenever he can, but when he gets into it, nothing can beat him. His traveling partner Nicolas Wolfwood completes the set as the embodiment of B (with some C thrown in), complete with a combination rocket launcher/machine gun/shotgun/pistol rack in the shape of a cross.
The Bernardelli girls: Meryl Stryfe, despite packing 50 derringers under her cape, is shown to be an A, able to aim accurately on the run. Milly Thompson (who normally carries her huge Stungun under her cape) would be a B if not for the fact her weapon is less-lethal.
Black Lagoon is an anime with two Gun Fu experts who use two pistols at close quarters as well as a huge number of gunmen (and women). One of those totes around a minigun...
More specifically, Balalaika is type A, Roberta and Gretel are type B, and Revy is type C.
Eda, who we haven't seen fight much, appears to be a type D. For evidence, in the episode Calm Down, Two men, she's a faster draw than Revy, though not by much. That itself should be noteworthy, considering Revy's considerable skill.
And everyone leaves out poor Mr. Chang, who is a surgeon with types A, C and D.
Rally Vincent from Gunsmith Cats is most definitely a type A. More bizarre tricks with a pistol than you can shake a stick at.
Rushuna Tendo from Grenadier also combines A and C into a uniquely anime gun-style, and at one point engages in a full-scale Gun Kata duel with a rival in the final episode.
Rushuna also covers type D. While wielding one six-shooter, she has outshot a multi-barreled machine gun by not only shooting the bullets out of the air but hitting them so precisely they then blocked entire chains of other bullets.
While her guns are very small, Natsuki from Mai-HiME is definitely a type B (since her CHILD can fire missiles and incredibly powerful beams of ice.) Her Mai-Otome counterpart gets a personal BFG.
Depending on the weapon he's using, Gene Starwind of Outlaw Star alternates between A (pistols), or B (machine guns or rocket launchers)
Usopp in One Piece somehow manages to be a Type A without ever actually using a firearm (at least not one using traditional chemical propulsion).
Apparently, he inherits it from his father, who, while we never see being engaged in any particularly amazing examples, brags about being Type A all of the time.
A villanious example can be found in Hol Horse from JoJo's Bizarre Adventure; a Type A, thanks to the fact that his Stand, the Emperor, is a revolver that lets him control the trajectory of its bullets.
From part 5 we have Guido Mista who's stand Sex Pistols manifest as 6 imps who guide his bullets.
Another example from the JoJoVerse is RingoRoadagain, a semi-villainous example. He's a very solid type-D. He has some Type A in him, but that's a subtle subversion. He knows the most accurate distance for just about any revolver out there and he never fires one step outside of that range, which is why he never misses.
In the anime Trinity Blood, most of the heroes gunsling quite a bit, particuarly the Guns Akimbo, M13 Jericho wielding android Tres Iqus who has all three styles pretty much nailed (given that Gunslinger is actually his callsign this isn't at all suprising).
In several displays of skill, Riza Hawkeye from Fullmetal Alchemist combines ALL FOUR of the above types. A is shown in her incredible long-distance sniping skill, while B and C are shown in her battles with the homunculi. Finally, D is shown in Roy's fight with Scar.
Brandon Heat/Death Beyond the Grave from Gungrave: while during his human life Brandon preferred type A, C and D, super-human strength of his undead state allowed him to carry big enough guns (the Cerberus handguns and the coffin) to add type B to the list.
Daisuke Jigen from Lupin III is an expert shot who uses a custom .357 Magnum revolver to be the Trick Shot, The Woo, and the Quick Draw (0.3 seconds). Because of his strength in an array of guns, including rocket launchers and sniper rifles (which he shoots from the waist in The Castle of Cagliostro), he also qualifies as The Vaporizer. He actually dislikes More Dakka, saying that shooting more shots isn't better, especially when one will do the trick. He proves it in Lupin III Stolen Lupin, where he has a broken gun, and one bullet. This, against an enemy with automatic weapons in each hand.
Lupin, Fujiko, and Zenigata are also good with their guns, but Lupin's the clear number two. His use of misdirection and disguise make him a better trick shot than Jigen, although many movies have Lupin's gun wrecked before he can fire.
Bleach: Primera Espada Coyote Starrk's released form is that of a traditional wild-west outlaw equipped with a pair of guns. For the most part, he has exhibited types B and C, albeit in a x100 fashion.
Suifeng's Bankai is a shoulder-mounted missile-launcher. Pure type B.
Ururu beat Starrk as the first gunslinger by hundreds of chapters. She's a type B.
The Stern Ritter have a Quincy who manifests his cross as a relatively ordinary looking pistol. This being Bleach, everything is but ordinary and the guy actually shoots out Shunsui's eye. Something even Starrk couldn't do.
Death the Kid is a combination. His usual style of a (literally) inhuman turn of speed, close-combat and Gun Fu falls under C, whereas Death Cannon and his other soul resonance attacks are B.
The Thompson Sisters themselves also fit the trope. While they're technically the weapons of Death the Kid, they've both shown the ability to fight using each other quite proficiently. Even more so now that Patty's become Liz's meister and Kid's possibly gone through a Face-Heel Turn.
C.T. Smith from the short-lived manga Zombie Powder; he had types A and C in spades, with a splash of D due to his super speed.
Synthetic Human Zoichi Kanoe, of Biomega, exhibits all types, A through D, in any virtually every fight he's involved in.
Child Soldier Jonah from Jormungand is both A and D, which is quite unnerving to his mercenary teammates due to his young age. He also is not afraid to do a bit of type B when the situation requires it.
In Kino's Journey Kino is a formidable quick draw, often seen practicing it and later putting it to use with very effective results.
Yoko from Tengen Toppa Gurren Lagann has elements of A and B. She carries an over-sized, high-energy sniper rifle with her wherever she goes..
Akane from Kämpfer is normally a nice, quiet girl. Upon her transformation into a Kampfer however, her Bad Ass side appears along with a gun, and then starts firing at pretty much everything in sight she decides she doesn't like.
Maya from Burn Up W/Excess. Being a Gun Nut, she's so crazy for her weapons that she gives them names. Type B, given that most of her arsenal qualifies as "big guns" and she has an itchy trigger finger.
Her Burn Up Scramble incarnation leans more towards a type A, showcasing more shooting skill and less desire to just shoot.
In Shikabane Hime, Makina's weapon of choice is a pair of MAC-11 machine pistols.
Medabots: KBT-type Medabots, including Metabee, are designed for shooting techniques. Metabee is both a Type A, with his precision-firing revolver on his right arm; and a Type B, with a quick-firing submachine gun on his left arm.
The Saint of Killers from Preacher is A (no matter how he shots, he will kill), B (infinite bullets) and D (apparently he doesn't even draw, he is instantly pointing at the poor guy who encounters him).
FBI Agent: So he drew on you and started shooting.
Sheriff Root: Ain't what I said. I said there was a blur and then shooting. I didn't see no draw.
Stan Lynde's comic strip Rick O'Shay featured introspective yet deadly gunslinger Hipshot Percussion, types A and D.
The protagonists in Sin City all use guns. Hartigan is Type D since he usually draws and fires a single shot without having to move too much (he is pushing sixty with a bum-ticker, afterall). Dwight is Type C. He usually has Guns Akimbo and does a lot of fancy footwork to avoid getting shot. Wallace is Type A, as evident by the fact that most of his shots are impossible to perform. At the end of his story, he shoots an entire warehouse filled with assassins before any of them manage to fire off a single round. Marv rarely uses a gun even though his is the most famous due to its name. From what we see, he's more of a quickdraw, Type D.
The Marvel Comics character The Two Gun Kid, being a displaced cowboy, is the embodiment of this trope in the Marvelverse, hitting both the A and D types.
Wynonna Earp tends towards C and D, with occassional elements of the other two.
The Mariachi from Desperado is a quintessential Type C with undertones of Type A. This departs from the Accidental Hero played straight in El Mariachi, who killed his adversaries almost unintentionally. Common to expanding characters in this trope, flanderization overtakes this character and others in Once Upon a Time in Mexico.
The Titular Character in Django Unchained qualifies as a D with hints of B during the bounty hunting montage.
In Maverick, the eponymous characters reveals himself to be a Quick Draw, but is not an actual gunfighter, preferring to bluff his way out of conflicts. This is in contrast to the original tv series, in which both the Maverick brothers are said to be incredibly slow on the draw. Bart once claimed that Bret could outdraw him any day of the week, and that Bret's nickname was "The Second Slowest Gun in the West".
Rattlesnake Jake in Rango is a combination of type B and D, and Rango claims to be a type A, and on one occasion, is one due to dumb luck
Pirates of the Caribbean Jack Sparrow is a type A. Most of the fighting he does is melee, but when he takes up a gun it's always to do a single shot which needs to count. To wit, he fires a gun once per film in each of the first three films note Shooting Barbossa just as Will breaks the curse in the first, shooting an powder barrel in the second, shooting Davy jones' chest out of his hands in the third.
In The Fastest Gun Alive Glenn Ford plays a store clerk who gets tired of the overblown stories of the townspeople and shows them how fast he is, shooting two silver dollars in the air. Unfortunately, this draws the attention of an outlaw who will start killing people if Ford does not face him. The truth is that Ford is the son of a famous sheriff who taught him to shoot, but he never worked up the courage to face anyone. He changed his name and hid from his past. In the end Ford has to prove himself.
Roycephus Pulsipher of the RIPD is able to shoot a two headed foe with both hands while both are jumping through the air.
Calamity is a solid type A, pulling off kill shots while performing complex aerial maneuvers, being the team's dedicated sniper with the BFG Spitfire's Thunder, and being skilled in magical energy weapons.
Steelhooves is type B taken Up to Eleven! His go-to weapons are a missile launcher and GRENADE MACHINEGUN! While his raw firepower is a great asset to his friends, it's also frequently an inconvenience as he leaves little to scavenge from.
Little Pip herself is something of a type C. Her telekinesis allows her to wield multiple weapons at once (not always guns even), makes frequent use of S.A.T.S to invoke Bullet Time, and her weapon of choice is a scoped revolver.
In Poké Wars, Dawn is mostly the type A but has some type C tendencies. Her supernatural accuracy places her in the type A category but her penchant for using dual pistols at close range places her in the type C category.
In Child Of The Storm the Winter Soldier falls into categories A and D with a touch of C - he's capable of moving fast enough to turn and shoot a master assassin who has snuck up behind him and is holding a gun to his head before the other man can even shoot. The type A is also sort of inevitable since his grandson is Clint Barton.
Roland Deschain of Gilead, the Last Gunslinger of Stephen King's magnum opus, The Dark Tower series. As it is fairly realistic in terms of gunplay, Roland only exhibits types A and D. He never has enough ammunition to be a B type (and would probably consider it to be obscenely wasteful), and is only a type C insofar as dual wielding (albeit briefly). Considering he's using single action revolvers, and could only dual wield by thumbing the hammers, doing it at all is quite impressive. Not to mention the only reason he stops Dual Wielding is because he loses two fingers off his right hand, and is rendered unable to hold a gun in that hand. Later, more gunslingers are added to Roland's ka-tet, all type A/D:
The Executioner. Mack Bolan has shown A, B, and even C tendancies at time, although not to a superhuman extent, as have his ripoffs homages like The Punisher.
Matthew Stark in Cloud of Sparrows is a somewhat more historically accurate version than usual. He's a dirty, coarse, violent man who nevertheless is good at heart. He's also able to out-reflex ninjas.
Holly Short and Vinyaya in Artemis Fowl. The latter requested for elecftric runs during a goblin rebellion despite not having to fight due to her desk job position but the same desk job position gives her a lot of power. She didn't miss.
Back in the early days of the Star Wars Expanded Universe, Han Solo had several run-ins with a professional gunman named Gallandro, a mercenary renowned for being the fastest gun in the galaxy. Exploits attributed to him include hunting down a crime family, single handedly hijacking a star-liner and forcing the Assassin's Guild to default on a contract (by hunting down and killing half of their Elite Guard).
In Chasm City, it was said of the protagonist that he could take out specific brain functions with a shot, making him a Type A. He laments to another character that he was never actually that good, but says he did come close.
Lt. Karrin Murphy of the Dresden Files is possibly this trope's Patron Saint. (Given the series, that could be literal — especially since she's almost certainly at the top of the very short list of candidates to become a new Knight of the Cross.) She wades into battlefields and underground lairs of the things that go bump in the dark, armed with only a gun, a badge, and five feet and pounds of Badass Adorable. Despite that, she's covered Harry's back with surprising success, doubly so for a muggle. She even gets her own chance at narrating in Aftermath''. She's much more matter-of-fact and practical about it than Harry.
Her narration notes that she can make instinctive snapshots. But only because of hours and hours and hours of practice down at the range.
She impresses Kincaid. The mercenary mentioned below, who was The Dragon to Vlad Drakul (Dracula's more badass dad) and has been the foremost and most most expensive hitman in the world for centuries. Which is all that really needs to be said.
The series in general averts most of the unrealistic parts of this trope. Humans miss sometimes, even if they're pretty damn accurate. Humans are fast, but not that fast, and nobody carries that much ammo. Humans have to practice to keep their aim sharp. Harry even ID's a notable supernatural hitman because the guy doesn't miss in a running firefight.
Harry was once given a holy-water paintball gun because he had the least firearms experience in the group. That said, he frequently carries a loaded firearm and practices regularly, and is more than willing to use one when it's less illegal than magic, or more convenient.
Supernaturals (e.g. Thomas and Lara Raith. Harry complains that he doesn't even practice, yet nails a target from over a hundred feet away with a pistol. On a boat. In Lake Michigan. At night) play this trope awfully straight, hitting points A, C, and D. Justified - they do have supernatural powers and are capable of absurd feats like grazing skin layers off with a shot, ignoring recoil, and blurring speed. Fortunately, magic is faster that bullets.
The more forward-thinking (younger) among the Wardens and Knights of the Cross are known to carry heavy pistols and assault rifles, and use them proficiently.
To the point where Harry draws his revolver in Dead Beat and suggests shooting Cowl in the back. Ramirez, young Warden poster boy and owner of a Desert Eagle and multiple grenades says this is why the young wizards like the way he thinks.
Chess Pargeter of Gemma Files's Hexslinger Series hits points A and D above, both killing a man with an over-the-shoulder shot without even looking and later shooting a would-be avenger twice (while sitting down) before the young challenger can even draw his pistol. (He does, however, have an advantage: unknown to him, he's a latent and partially-manifested "hex", a ridiculously powerful natural magician, and has been unconsciously channelling his powers into his gunplay.)
Criminal Minds has Aaron Hotchner, Elle Greenaway, Emily Prentiss, and Jennifer "JJ" Jareau, all of whom are incidentally very good shots (Emily is probably the worst shot out of all of them, but that's not really saying much, since the only time she's ever really *missed* was about thirty seconds after getting a concussion in a car crash). Hotchner is notable for wearing not only a pistol on the belt, but in his boot while in the field. JJ once even killed an UnSub with a perfect headshot through a glass-paned FBI door. Technical Analyst Penelope Garcia has only held a gun once.
Mal in Firefly exhibits D to some (humanly possible) degree, gaining quicker draw and better aim the more pressure he's under. His two partners, Zoe and Jayne, tend toward A and B respectively, with Zoe providing the pinpoint accuracy and Jayne providing the Dakka.
Zoe might be the character known for accuracy, but Jayne seems to be even better at it than she is when he's trying. Most notably, he's the only member of the crew to ever use a sniper rifle: in the first episode, where he shoots the hat off his target.
Red Dwarf: Thees ees a chob for the Riviera Kid!(funny dance)
Farscape's Aeryn Sun. Especially impressive when compared to the male lead, who attempts to fire a gun only to have to throw it away as it explodes. Even after taking a few levels in badass, said male lead is nowhere near Aeryn's level when it comes to gunplay (Aeryn wouldn't trust him around her BFG until things got really desperate—to his credit, during that instance, he finally handled the thing competently).
Mossad liaison Ziva David from NCIS. Always lethally skilled with firearms (and everything else up to and including Kleenex and rubber bands), in an episode she exhibited the ability to dual wield a semiautomatic pistol and a revolver (at 90-degree angles to each other, no less) in a shootout to protect a Federal witness in their hideout hotel. Result: two dead Mooks, dead via simultanious Pretty Little Headshots, and Ziva, not so much as scratched, calmly reholstering as McGee and the terrified witness crawl out of the hotel bathroom.
Kamen Rider has one for each season. Rarely two gunslingers. Usually, the rider has a weapon that can change into a gun.
Power Rangers Lightspeed Rescue almost always resort to using their guns. In fact, they have more gunplay than the other teams. Justified due to the fact that it was a military operation, not some wizard, granting the rangers these powers.
Kid Curry from Alias Smith and Jones shot the gun from another gunfighter's holster before the man could draw.
The Lone Ranger tended to shoot guns out of bandits' hands with either hand.
Doctor Who has River Song, who likes energy handguns, and once used them to threaten the Roman Army into helping her. Liz 10 also carries two Steampunk laser pistols.
The Doctor's full-time companions generally avoid guns, but some of them end up here anyway. Sarah-Jane demonstrated surprisingly good marksmanship for a reporter in Pyramids of Mars, Ace took out a Dalek with a rocket launcher (she aimed for the eyepiece), and both Rose and Martha have got in on this in the revival.
On Mythbusters, have you ever noticed that when the build team is testing a gun myth, Kari Byron tends to bring the biggest weapon to the party?
Kari said in a behind-the-scenes interview once that, being a good Californian, she was very anti-gun before working with Mythbusters, and after their second or third gun myths special, she found that she had turned into a gun nerd along the way. She now privately owns several firearms of her own and never seems to be far away when they're testing gun myths on the show.
Clint Wayne and Angel Eyes in Dino Attack RPG are a duo of gunslingers. The former is shown to be type D but is likely also type A, while the latter is also type D... with a rifle. Atton Rand openly admitted that Clint Eastwood and Lee Van Cleef's performances in Sergio Leone's Spaghetti Westerns were a major influence for both.
Quite popular in the Necromunda setting. Among the House gangs, if you're not a Gunslinger, you're probably a Young Gun. You have rifle-wielding snipers for Type A, heavies who carry one of a variety of BFGs, or a melee fighter who dual-wields pistols or a pistol and close combat weapon.
The notorius Cypher of Warhammer 40,000 is well-known for wielding a pair of exquisitely crafted pistols (not similar; one is a bolt pistol, the other is plasma).
Not to mention outdrawing and killing one of Abaddon's Terminator bodyguards so fast that even Abaddon nearly missed it.
It's reflected on the tabletop too - he was the only character in the game that could fire both pistols twice in one turn.
Sisters of Battle (Witch Hunters) give us the Seraphim, power armoured ladies with jetpacks who dual-wield automatic microgrenade launcher pistols. Or, alternately, dual wield flamer pistols, or, if you really want to splash out, microwave pistols that can turn a super-heavy tank into slag. Their gun fu is so awesome that everyone around them feels just a little bit braver for having them there.
Most armies have got some characters specializing in gunfire:
Marneus Calgar, possibly, with submachinegun microgrenade launches strapped to his forearms. Definitely a Type B.
Maugan Ra is a Type B, carrying by himself a heavy machine gun that normal Eldar have to strap to an anti-gravity platform to lug around and is easily twice as effective as Shadowsun or Calgar when facing enemy infantry.
Commander Shadowsun also qualifies as a Type B, assisted by power armor, what with carrying two anti-tank weapons.
Dark Eldar tend towards the choppy end of the scale, but their Haemonculi can carry a device called a Hexrifle: a sniper rifle that turns the target into a statue.
The Imperial Guard have more than most due to their shooty nature, but special mention must go to Type D Guardsman Marbo and his sniper pistol, and Type B Gunnery Sergeant Harker, who carries a heavy bolter (a weapon normally carried by two men and fired from a tripod) around.
The Vindicare Assassin is a classic Type A, as he is at the moment the only model on the table that can single out a specific model in an enemy unit with a gun and blast a hole in his head, and carries special ammunition that lets him do things like make tanks explode with a sniper rifle. In Dawn of War, an infiltrated Vindicare Assassin is possibly the best secondary commander unit in the game.
It would be remiss not to mention 'Slick' Devlan of Inquisitor.
Don't forget the characters spiritual successors from Dark Heresy, the class of Scum hailing from Gunmetal City on Scintilla.
Anyone with Gun Schticks and/or a high enough Guns skill in Feng Shui is a Gunslinger in terms of this trope. Maverick Cops, Killers, and Ex-Special Forces guys are especially exemplary of the trope, but Spies, Gamblers, Magic Cops, Masked Avengers, Monster Hunters, Cyborgs and even Medics can qualify as well, along with any other archetype who spends XP on Gun Schticks and the Guns skill.
What type your gunslinger character generally is depends on what Gun Schticks you give your character. Trick Shots prefer Eagle Eye, Shoot Weapon, Sabotage Shot and other schticks that allow them to perform crazy feats of accuracy. Vaporizers generally go for Carnival of Carnage and 10,000 Bullets to maximize the mook slaughter, along with Cover Fire, Bullet Storm, Lightning Reload, Who Wants Some, and a good automatic weapon capable of More Dakka. Woos can use pretty much any schtick out of the books, though Both Guns Blazing, Carnival of Carnage, Slow Mo Vengeance and others are primarily used by them. Quick Draws, as per the name, generally buy up lots of Fast Draw in order to act ahead of everyone else in a given sequence.
One of the more common character types in Deadlands. Some hucksters (called 'hexslingers') combine magic with gunplay to give them an extra edge.
The aptly named advantage "Gunslinger" in GURPS makes you into a type A, C or D.
There's a Gunslinger O.C.C., in the Rifts megaverse. Specifically, they can be any combination of A, C, or D. In-game fluff describes them as assassins, hitmen, and mercenaries who specialize in close combat and dual-wielding pisols. They also have a psychic equivalent, the Psi-Slinger.
Shards of the Exalted Dream gives us the Solar Firearms tree, which has stuff for all four types (as does its Abyssal mirror). What's especially hilarious is that with sufficient strength, you can use the Guns Akimbo Charms, Sun-Dog Gunslinger Stance (Solar) and Murder of Crows Posture (Abyssal), while dual-wielding godcannons, which are guns the size of men.
Pathfinder now has the Gunslinger class, which uses flintlock pistols and muskets (and whatever else Paizo comes out with once playtesting is done). Gunslinger characters have a resource called Grit which is used for pulling off crazy gunslinging stunts and is replenished with daring deeds, as the Gunslinger is not just a class about shooting things but a class about being really ballsy while you shoot things.
Heroscape has several according to their bios, but only Deadeye Dan has actual effects that make him this. He's a type A who has two abilities: one which gives him a half chance to deal one damage (which is deadly to characters with one life and high defence) and the other which gives him a one tenth change of instant killinganyone.
The Greyhawk portion of Dungeons & Dragons gives us Murlynd, demigod of Magical Technology, and his White Paladins. Murlynd himself is styled after a Wild West sheriff, and he and his clerics and paladins are the only ones who can wield firearms in the setting.
In d20 Modern, there is an actual advanced class called Gunslinger. Unlike most fiction gunslingers, his abilities are mostly Boring, but Practical: Getting untyped bonuses to attack rolls (Type A), increased benefits from cover. He can also shoot more often than other characters (type B), and is such a good shot that he reduces cover bonuses his enemies gain against him (type A).
The Iron Kingdoms gun mage is a gunslinger with magic; a sorcerer who uses his or her specially made rune-engraved firearm (typically pistol/s, but a few can use rifles) as a focus for spellcasting. They can imbue their bullets with spells, allowing them to pull off all sorts of trick shots and effects, from shooting through walls (Type A) to creating a localised lightning storm where the shot hits (Type B). They exist as Cygnaran and Mercenary models in the wargame and as a playable class in the RPG. The most famous signature character gun mage, Allister Caine, is also adept at teleportation magic, making him a capable Type C and D as well.
Samus Aran of Metroid, as well as her Zero Suit incarnation.
Thugs Masterminds have access to a few pistol attacks.
The Dual Pistols powerset features type A attacks and a couple of type B attacks such as firing bullets in the sky so they rain down on enemies.
Dungeon Fighter Online has the gunslinger class that can advance into Three Type B's: The Launcher, that specializes in heavy weaponry; Mechanic, that builds robots that either explode or shoot things for him/her; Spitfire, that can use special rounds and explosives; and a Type C/D, Ranger, that uses melee kicks and and quick shots.
The Metal Gear Solid series has an example of each. Revolver Ocelot is a Trick Shot, Vulcan Raven is a Vaporizer, and The Boss is a Woo. Snake himself is a Quick Draw, but it almost never comes up.
The Boss is C and B. Look at The Patriot: a rifle with the barrel cut short. Size of a pistol, power of the rifle, and infinite ammo. Yes, the infinite ammo part is canon. And yes, she takes full advantage of it. She also takes away your gun, takes it apart, and hands you back the pieces.
Jr. from Xenosaga plays this trope straight, wielding Guns Akimbo in the Type A style. His special attacks tend to involve ricocheting bullets off coins to the point in one of his moves, he throws more than a dozen coins, fires a single bullet, and the bullet bounces off every coin hitting every enemy.
Billy in the Spiritual Predecessor Xenogears is another Gunslinger, mostly Type A style or maybe C depending on playstyle. He is also one of the best healers in the game by virtue of being a priest or training to become one. Notably his last deathblow forgoes the main types he displays (A and C) and delves straight into B where he unloads every gun he's carrying and even briefly jumps into a FPS-like view while firing his handguns before finishing with his shotgun.
Sundown from Live A Live is a Type B (see his ultimate attack, Hurricane Shot, which fires more bullets than any four revolvers should ever be able to carry). Of course, he's ALSO a Type A (Multi-Counter, which animates as him turning his back to the enemy and shooting through his poncho as a counter to almost any attack, and Pierce Shot, which hits all enemies in a line). In universe, Sundown is also a Type D, as he's described as having "an arm as quick as lightning" (Neo Shot Storm, which can hit up to around six times, all before his opponents can react). Mad Dog, from the same game, is also a Type A, as all of his attacks are essentially trick-shots.
Dante from Devil May Cry blends all four types together - A with near-flawless accuracy and Offhand Backhand shots, B with crazy rate of fire and a variety of explosive weapons, C with his superhuman agility and D with the ability (both in and out of cutscenes) to draw quickly yet still fire accurately. Of course, he has a Style explicitly named Gunslinger that enhances his firearm moveset. Nero aspires to reach the same level of competence, but isn't there yet.
Created by the same person who created Devil May Cry, Bayonetta takes all 4 types to truly outlandish degrees. From regular hand guns to shot guns to ROCKET LAUNCHER TONFAS, and so many other weapons, Bayonetta is currently one of the most insane examples of the gunslinger in video games so far.
Noel Vermillion from the Blazblue series is a textbook Type-C. Lots of emphasis on Type-C, because gameplay-wise, her long-range game is pitiful. Most of the damage coming from her guns are either short-range blasts or hitting people with them, rather than anything that resembles a traditional ranged attack, and is bad at zoning overall.
Reaver from the second Fable game is type A and D. Makes sense, considering that not only is he the Hero of Skill, but also that by the time you see his fighting skills in action, he's had hundreds of years to practice his shots.
Your player character itself is a type A, as maxed skill lets you hit from any distance, and kill with one shot.
The Time Control spell lets you move toward the C and D types by dropping a pack of bandits before they have time to get their guns out.
Boktai, anyone? Both Django and his spiritual successor Aaron use Solar Guns, drawing from all three schools. In Aaron's case, the Witch is the Trick Shot, the Ninja is the Woo, and the Bomber, Dragoon, and Knight suit the Vaporizer fine.
Since all of the leads in Wild ARMs 3 had AR Ms they almost got to be class representatives each:
Jet was the Type B, equipped with the machine gun - though in-game he could be considered a partial D too thanks to having the best speed.
Clive was the Type A, no fancy tricks but was the most accurate bar none thanks to his sniper rifle
Gallows...was unique...he carried a shotgun but his skillset was geared to magic use instead of physical combat. If in a pinch, his standard attack was strong enough to make him a lesser Type B (instead of pumping enemies full, each single hit compensated for lack of dakka).
Virginia was a combination of all the classes and her status as something of a Jack-of-All-Stats in-game shows it.
In Wild ARMs 5 we get Dean, an exemplary Type B primarily with a dose Type C for good measure and Rebecca who is a picture perfect Type A (she even says aiming to be a master trick shooter) with a dose of Type C.
And also The Sniper. Shooting someone through the head to smash a bottle held by the guy standing behind him, causing him to misfire and blow up the building they're standing in? Classic A all the way.
Given his reaction, and the previous scene showing that the first guy was the target, that was probably an fortuitous accident.
Which type the other characters can be generally depends on the player's particular style. The Scout lends himself to a type C playstyle, while the Spy is best off as a type D.
Don't forget The Pyro, who gets to switch weapons more quickly when he/she has the Degreaser equipped, allowing him/her to be a type D quickdrawer....with a shotgun!
Carth Onasi in Knights of the Old Republic and Atton Rand in the sequel both have elements of types B and C, stretching into type D during some cutscenes.
The Kid in Bastion is a combination B and D with dueling pistols (With a side of C in that he dual wields.), being capable of drawing, locking on and emptying both guns into anything essentially as fast as you can click. One special attack moves into A territory. He also gets bonus points for reloading solely by Gun Twirling.
Use of the Scrap Musket can put him squarely into type B, particularly with the special attack unloading around half a dozen shots in rapid succession. From a single-shot, muzzle-loading, shot-firing musket. There's also the Army Carbine and the Fang Repeater, the latter of which is A and B thanks to a high rate of fire and homing projectiles when appropriately upgraded.
The main character from Video Game/Fallout Tactics could be made into a Type B in turn-based mode. Start with a high agility character who takes a starting trait which lowers the AP cost of shooting, which can later be coupled with a perk that further reduces the cost and another that halves reload time. Since the game's revolvers inexplicably shoot faster than all other pistols, using one you can fire six shots, reload, then get off three more before the other guy even gets to move. And when not using turn-based mode, your character's shooting animation is slightly quicker than normal, making him type D. Nifty as enemies flinch and are stun-locked even from small damage, so even a huge mutant soldier can be cut down by one dude with a six-gun.
Gilder from Skies of Arcadia is a definite Type C. His first S-Move is even called 'Gunslinger'.
Max Payne is Type C. Really, all that was missing from the game's bullet-time antics were the frickin' doves.
On the occasions the player gets to take control of her, Max Payne's Mona Sax shows why she's notorious as a cleaner. Her default weapon is a Desert Eagle (which can be dual-wielded) and her sniping rifle of choice is a Dragunov.
There's a whole class of these in Ragnarok Online, with any one of the types available depending on how you build one up and what weapons you use.
Call of Duty: World At War has an achievement named 'Gunslinger' for performing some Type A marksmanship. At the end of one level, you must snipe an enemy General about a hundred yards away trying to escape a battle. While normally you have a sniper rifle for this sort of thing, the achievement is only gained if you use a pistol.
Another Type A achievement in the same level is gained for clearing a street of enemies without reloading - only problem is that the street has seven soldiers and an attack dog, and your rifle has a five-round magazine.
The nameless Gunslinger from the point-and-click PlayStation and PC game Silverload. He does not fit neatly into any of the types because he's controlled by YOU, plus the fact you have limited ammo for the shooting scenes. Good players can turn him into a Type A/D.
Rubi Malone of Wet is a Type A/C Gunslinger who likes to do acrobatic Gun Fu combined with up-close and deadly katana work.
One of the three skill trees for Mordecai in Borderlands is called Gunslinger, and focuses on pistol and revolver skills. The highlights are getting shots that do 100% more damage after a kill and occasionally getting a free bullet.
Barret Wallace and Vincent Valentine from Final Fantasy VII. Barret is a type B mostly while Vincent is a type A and type D but sticks to using only one gun rather than two, though thats due to the armored gauntlet on his left arm. Whether Vincent counts as a proper Gunslinger or just a guy with a gun, since he doesn't have any special moves that use it in the original game. If you accept everything in The Complication ofFinal Fantasy VII, then he could count, but his main power is still Voluntary Shapeshifting.
Irvine Kinneas who can be many different types on depending on the ammo type he uses and Laguna Loire who is a Bad Ass Normal who is a type B with his signature machine gun.
Lightning pulls off enough trick shots with her gunblade to qualify for type A. One of her normal attacks is shooting an enemy mid-backflip. Sazh isn't nearly as skilled at using guns as the other entries, but has some elements of B and D.
Commander Shepard of the Mass Effect series falls into every category if you play as the Soldier Class; Adrenaline Rush allows Shepard to hit nearly any point of an enemies body (Type A), The Revenant has an insanely large ammo clip and will completely obliterate anything in it's path (Type B), Shepard, as previously stated has Adrenaline Rush which slows down time to a crawl allowing for completely domination in CQC (Type C), which will also allow Shepard to kill enemies before they're even aware of his/her presence.
If you're an Infiltrator, your main gun is the sniper rifle, letting you pull of some Alan Quatermain Type A shots.
In cutscenes, every Shepard is a mix of Type A and D, being able to pull off very impressive shots and doing so very quickly.
As far as supporting characters go, Garrus is a mix of Type A and Type D (during his Establishing Character Moment he headshots a hostage-holding thug without harming the hostage, and without looking), Legion is a serious Type A, and in the third game Ashley is a massive Type B thanks to the Marksman power, which significantly boosts her firing rate for a short time- combine it with a fast firing gun with a large clip like the Revenant or the N7 Typhoon and she'll put out an impressive wall of suppression fire.
Raul Tejada, Type D. Completing his quest a certain way will get him an outfit/perk that lets him shoot even faster.
Arcanum: Of Steamworks & Magick Obscura allows the player to act as a Type B (with firearms with enough firerate) and/or Type D (with a long range rifle or handgun, especially if you play in turn-based mode).
Saika Magoichi from Sengoku Basara, being basically a Walking Armoury, can fulfil most of the above roles, but is closest to Type B. She commonly carries around magnums, a shotgun, a tommy gun and a heat-seeking rocket launcher (detonation charges or air support optional) and uses a combination of them to blow her enemies to bits.
Her predecessor Nouhime, despite also being a Walking Armory was more of a Type C with a focus on Gun Kata-like moves.
Any female character in Valkyria Chronicles has a portrait shot in the Personnel tab showing them in dramatic poses with guns. Props go to Sniper Marina who after a successful snipe-shot loads her gun onto her shoulders and tosses off a bond-one liner.
Tanya from the Command & Conquer: Red Alert series, who has a lot of fun killing enemies. She also packs C4 for blowing up buildings and ships.
C&C has other examples as well. In Tiberian Sun's campaign, there was Umagon, a mutant Action Girl who was available in certain missions. In Tiberium Wars, Nod's Commando was a Femme Fatale with an invisibility suit and dual lasers. And in Red Alert, the Soviets countered Tanya with Natasha, a Cold Sniper who could also call down airstrikes.
Interestingly, Mira in Knights of the Old Republic 2 is the only female party member in the entire series who specializes in ranged weapons instead of melee weapons, despite this articles opening quote. Technically, she can be equipped with other weapons like most party members including a lightsaber if you turn her into a Jedi, but she's always most efficient with a blaster or two in hand.
Lara Croft carries a pair of pistols in addition to her...other assets.
Bea from Lunar Knights is the only female of the Three Gunslingers. Her weapon of choice is the Witch. There are other female Guild members who use standard-issue Solar Guns based on the Knight as well.
Aya Brea, the heroine of the Parasite Eve series. She's also got some deadly magic to back her up; in the sequel one of her spells is to simply boost the power of her gun's bullets.
One of the targets hunted by Jango Fett Star Wars: Bounty Hunter is a gunslinger named Longo Two-Guns. His gang occupies a town on Tatooine, resulting in a level not unlike an old western movie.
Grit in Advance Wars would appear to be this, being the indirect combat specialist (though even the direct combat units use guns...) of the series, and he even carries a gun in his portrait. His mannerisms seem to be based on a Western hero.
In Guild Wars 2, half the classes can use guns, but only the Warrior (with rifles) and the Thief (with pistols) really fit this trope, which usually overlaps with The Musketeer after weapon-switching gets unlocked.
Blood's Anti-Hero protagonist Caleb is described as a gunslinger in the manual. In the game itself, the closest thing to a revolver he uses is a flare gun.
Wild Star has the Spellslingers, a magical variety who use mystic runes, the power of the universe, and their own sharpshooting to devastate their opponents.
Amical from morphE is so good with a gun that he can fire ten shots at five people with each bullet aimed perfectly at their respective hearts and foreheads. He is also a powerful enough of a mage to stop all ten bullets before they reached their mark.
This trope is the claim to fame for Pico of Newgrounds. Most often, he's a Type B, preferring an AK-47 or a brace of Uzis to blast his opposition.
Or Eldritch, looks like a young woman, shoots like a psychotic heavy-weapons range instructor; Generator might qualify too depending on your definition of 'girl', Loophole is quite proficient with her .45 handgun, and Bladedancer is secretly training with guns to surprise her opponents, while Bunker specializes in explosive ordinance (Girl With Bazooka)... considering the setting and the fact that training is readily available it's not uncommon to come across a girl that packs a gun or at least is proficient with one.
Annie Oakley. Legend has it that she could pin an ace of hearts card to a tree, walk twenty yards away, then shoot the heart right out of the center.
Wild Bill Hickock served as a marshal during the height of the Wild West. He was so fast with his guns that he was able to fend off an ambush in what is really the only "Showdown at High Noon" type of gun battle on historical record.
The White Tights of urban legend, an Amazon Brigade of blonde, white-clad sniper women with a hate-on for the Russians.
D. A. "Jelly" Bryce. He began his career with the Oklahoma City Police Department, for which he "interviewed" by fast-drawing and shooting a target group that could be covered with a silver dollar. He was recruited by the FBI after J. Edgar Hoover himself waived the "must have a college degree" requirement in order to hire the guy who was known to practice his fast-draw in front of a mirror for eight hours straight at a time. As a "special negotiator", brought in to deal with hostage situations and stand-offs—with terminal consequences for the suspects who chose to try to out-shoot him—he became so well-known and so feared that law enforcement only had to call him to the scene and suspects would surrender without a fight. In 1945, the magazine Life ran an article on Bryce, featuring a series of stroboscopic photos that documented his speed demonstration of holding a coin at his shoulder height, dropping it, drawing his gun, and shooting the coin before it passed the level of his waist. That trick shot only took two-fifths of a second.
