Gun Porn describes a scene or scenario with a lot of guns, enough to make a gun nut cream their pants (even women). In video games, there's also the option to see highly detailed models of said guns. Optional features include a careful attention to detail to the background and operation, heck, there might even be Bullet Time glory shots during the firing of a gun. Basically, someone decided that focus to the gun itself is very important.
It's basically the gun equivalent to Scenery Porn and Costume Porn. Close cousin to Technology Porn. Sometimes associated with Description Porn. See also Gun Accessories for more of the toys that go nice with guns. Not related to Phallic Weapon... usually.
Kenichi Sonoda's Gunsmith Cats, which is even about actual gunsmiths. He then went on to create the Super Robot series Cannon God Exaxxion, whose title mech is basically a 500 foot gun with limbs & a head. Some of his works feature 'literal' Gun Porn, like the heroine licking the barrel or a naked girl holding a rifle in a... strategic way.
Whenever Toriyama drew a gun in Dr. Slump, more often than not it was rendered in greater detail than the character holding it (though it usually still looked cartoony enough for the style of the manga).
Despite the Sci-Fi setting, Cowboy Bebop features mostly real and accurately drawn contemporary weaponry, with Jericho 941, Glock 30, Walther P99, HK USP, and 1911-style firearms shown impeccably drawn in prominent roles.
Hellsing - Kouta Hirano's guns are fictional, but the way he rattles off specs in such glorious detail... Dirty Harry would be proud. Seras's Harkonnen also deserves mention.
Alucard: "The silver cross of Lancaster Cathedral was melted down to create these 13mm explosive shells. Nothing I shoot ever gets back up again."
Walter: "Mercury tips. And they're already blessed."
Seras is a bit less appreciative of this when introduced to the Harkonnen.
Walter: "The Harkonnen: A 30mm anti-freak cannon. Designed to be used with both depleted uranium shells and exploding incendiary shells. This weapon will destroy all but the most heavily armored of targets."
The first Ghost in the Shell movie includes a scene towards the end, that shows the main character disassembling her PDW and ejecting the steaming hot barrel to switch for another calibre and armor piercing bullets. The same scene also includes a tank with two massive Gatling guns and a grenade launcher shooting the place to shreds.
Black Lagoon is a very gun-laden series, and Rei Hiroe is very good at rendering the main characters' primary instruments of destruction.
Desert Punk, though much more in the manga, which even has a section at the end of the volume collections listing details of all of the guns used including their action and rifling. The foreword of the first chapter even has the author stating how it would suck to be a gun in the desert because of sand getting in the barrel and the oil being affected by changing temperature.
Trigun, as you'd expect. Look at the Expy Ak-47s, magnums with barrels about eight-inches long that can morph into a super weapon, crosses that can become light machine guns, sniper rifles with barrels ten yards long, saxophones that can become guns, amongst other colorful examples.
Jormungand, as expected for a manga about a team of mercenary arms dealers. It features a wide variety of well-drawn hand guns, submachine guns, assualt rifles, sniper rifles, and a Javelin missile launcher all in the first chapter.
Hidan no Aria has every character (revealed till now) wielding different models of firearms, most of them described in great detail. While the usage of guns in the series sometimes lapsed into the Rule of Cool, the effort spent in describing their relative strengths and weaknesses is impressive.
Shaman King. The X-Law armory is filled with realistic weapons, ranging from RPG's to M16's. And to top it off, There's a giant angel Oversoul, right in the middle of the room, for Lyserg.
Upotte is an anime about personified firearms. Naturally, it includes very detailed depictions and trivia about the guns the characters represent.
The author's notes in the side story, Upotte!! Rufuira, show that the author is a genuine Gun Nut, who sadly is limited to owning deactivated guns on account of living in Japan.
The Walpurgisnacht/ Walpurgis Night battle at the end of Puella Magi Madoka Magica features some elements of this, most notably the sequence involving hundreds if not thousands of VERY accurately-drawn AT-4 and RPG-7 rocket launchers and due to Homura's time-stopping abilities, detailed freeze-frames of the rockets in-flight. See for yourself.
What about Pumpkin Scissors? Notably the .51 caliber PISTOL known as the "Door Knocker".
Fullmetal Alchemist has shades of this, especially early on - note the vastly oversized chain gun used by Father Cornello in the first chapter, and the automail gun used by the bandit leader in the train heist - as well as more conventional instances like Riza dismantling her pistol.
Aliens futuristic Pulse Rifle and Smart Gun were basically just modified Thompsons SMGs and MG42s.
Shoot 'em Up is an obvious attempt to go as far over-the-top as possible with this trope. It goes so far over the top that it becomes an Indecisive Parody. The movie is meant to be antigun, but this intended moral falls completely flat.
While omitting the obsession over guns themselves compared to actually using and discarding them, which makes it, um... hardcore gun porn?
Lord of War, being about an international arms dealer, is rife with Gun Porn.
Shooter (the Mark Wahlberg movie) is basically one long excuse to show guns
In Wanted, the main characters (protagonists and antagonists alike) have the ability to curve bullets fired from a gun. One can only imagine what gun porn potential this unleashes. Needless to say, there are a multitude of glory shots of bullets being fired and close ups on what kind of destruction they cause, often times amounting in little more than duels with guns, as the characters sometimes deflect bullets by firing other bullets at them.
Several of the scenes in Predator, particularly the famous deforestation sequence, were meant to ridicule this trope.
The Terminator series is full of gun porn. T2 is a particular offender, with lots of shots showing Sarah Connor's humongous underground gun vault, and then there was her coffin in T3 that was filled primarily with loads and loads of weapons. There's also the whole scene where Arnie destroys dozens of cop cars with a minigun.
District 9 contains many cases of Gun Porn, often from previously rarely seen South African small arms, most notably the Denel NTW 20mm anti-materiel rifle and PAW 20mm grenade launcher, both of which were used to finish off the mech.
The armory of the Swiss Guard in Angels and Demons is half Gun Porn and half Flanged Mace Porn.
The back of Reese's van in From Paris with Love presents a special cache of this, once you get past the keypad.
Played for Laughs in Boondock Saints 2 which has a scene where the Saints are choosing their weapons for a hit. The weapon provider invites them to see his best stuff, and when he opens the briefcases, actual softcore porn music starts playing.
Tremors has an actual fan of Gun Porn in Burt Gummer, and a scene in which his compound is attacked by the subterranean beasty breaking into his basement. It starts with him and his wife unloading the guns they were cleaning into it, then running out of ammo and backing toward the far side basement wall which is absolutely covered in guns in what can only be described as a Crowning Moment of Funnyand a Crowning Moment Of Awesome wrapped into one. That Graboid broke into the wrong goddamn recroom.
Just prior to the climatic finale in Hot Fuzz, Angel loads himself up with an enormous array of weaponry acquired earlier in the film, all presented in fast but loving detail, with loading them with ammunition, cocking and twirling galore. In one of the DVD commentaries the director faux apologizes for saying so, and remarks he must be a 14 year old boy, but he claims the sequence gets him hard. Sounds like gunporn alright.
Big Daddy's studio-stroke-armoury in Kick-Ass fits the bill - racks and racks of beautiful weapons, including a number of rare items. And, wonderfully, a jetpack-mounted twin-minigun rig. Mmm...
Iron Man 2, when Hammer shows Rhodey and a general the weapons he can offer in exchange for an Iron Man suit. When asked which of the large arsenal he wants installed in what will soon become the War Machine armor, Rhodey naturally says "all of them."
Zardoz, the titular god says "The gun is good!", and literally spews thousands of guns and bullets for his followers to use.
Unforgiven, while being essentially a deconstruction of the whole western genre, still manages to prominently feature a wide cross-section of old-west firepower. Several of the weapons (such as Ned's Spencer rifle, the Kid's Smith & Wesson Schofield, and a mentioned but unseen Walker Colt) are identified by name.
In The Mask the title character takes out from his pockets around fifty different guns and aims them at the mooks. After they run away however, it is revealed they are all Bang Flag Guns.
Most openings of James Bond films combine this with silhouettes of dancing girls (usually wearing Vapor Wear).
The Good, the Bad and the Ugly has some very loving close-up shots of revolvers being disassembled, cleaned, reassembled, with some chill-inducingly satisfying foley.
In one of the most awesome acts of self-defense ever depicted on film, there's a scene in The Dark Knight where a hostile witness tries to kill Harvey Dent, but the gun misfires, and then he punches out the witness, grabs the gun, and lays it in front of Sal Maroni with these words, including a succinct description of the attempted murder weapon:
Harvey Dent: Carbon fiber .28 caliber, made in China. If you want to kill a public servant, Mr. Maroni, I recommend you buy American.
In the novelization, it's ceramic, not carbon fiber.
In xXx, Xander points to a huge pile of guns (and other stuff) and then to his car saying "I want all that, in there!"
The Death Lands series usually has elaborately detailed descriptions of guns. If the Armorer is featured in any way, expect elaborately detailed descriptions of all the parts of those guns.
The Mack Bolan series usually have trading-card stats of relevant weapons. Plus every Cool Gun in the planet must have been used by the protagonists at one time or another.
The Guardians series often has plenty of loving descriptions of military weapons, vehicles and explosives, how they work, and how soldiers using them rate them. Almost all present-day weapons, despite the setting being Twenty Minutes into the Future — or it was, when the series started. Now it's Alternate History.
Neal Stephenson takes this trope, in written form, to his heart. In Cryptonomicon, he spends over two pages lovingly describing the Vickers Machine Gun; The gun has its own little story arc, complete with an entire page of building action, climax and denouement. This is merely a callback to Reason in Snow Crash, a portable gatling cannon that's described in loving detail several times throughout the book.
The Vickers was water-cooled. It actually had a fucking radiator on it. It had infrastructure... and a whole crew of technicians to fuss over it. But once the damn thing was up and running, it could fire continuously for days as long as people kept scurrying up to it with more belts of ammunition... Mikulski hosed down all of the German vehicles for a while, yawing the Vickers back and forth like a man playing a fire extinguisher against the base of a fire. Then he picked out a few bits of the roadblock that he suspected people might be standing behind and concentrated on them for a while, boring tunnels through the wreckage of the vehicles until he could see what was on the other side, sawing through their frames and breaking them in half. He cut down half a dozen or so roadside trees behind which he suspected Germans were hiding, and then mowed about half an acre of grass.
William Gibson goes the other way in Neuromancer; He writes Gun Gorn: He describes in great detail all the horrible things that have been done to weapons to make them into Saturday Night Specials, down how their barrels have been mutilated and abused.
Matthew Reilly usually introduces his bad guys with this, so that the audience knows how awesomely the protagonists are outmatched.
The 1980's action-adventure series The Survivalist, written by gun writer Jerry Ahern.
Fate/Zero's author Gen Urobuchi gave a whole lot of detail to the weapons that Kiritsugu Emiya uses. To wit, Kiritsugu's weapons are a Calico M950 sub-machine gun, a Walter WA 2000 sniper rifle (with night scope and heat vision sensors), and his Mystic Code the Thompson Contender, customized with his Origin Bullets. The anime also shows other weapons in a couple of lock and load montages.
J.T. Edson always describes the weapons of his protagonists in loving detail. No character ever carries a generic gun, and the advantages and disadvantages of a particular weapon choice will always be spelled out.
The Zombie Survival Guide is full of this. Even the guns that wouldn't be the best for killing zombies are described in detail.
Name practically any Baen book that involves the citizens of Grantville, Thuringia.
Blokkmonsta's "Das ist meine AK" (This is my AK), a German rap song, is basically this in the first verse, listing a lot of factoids like weight, magazine capacity, maximum range of the projectile etc. The second verse is sung by somebody else who just raps about how he will kill you very hard with it.
The GURPS: High-tech source book has almost a third of its width dedicated to explanations, rules, tables, and descriptions of various modern guns.
World of Darkness: Armory is pretty much gun porn, breaking down the standard firearms listed in the core book (light pistol, heavy pistol., shotgun, SMG, rifle, assault rifle, etc.) into make, model, and special properties. And then it gets into Melee Weapon Porn, Explosives Porn, Vehicles Porn... basically, it's the book to bust out when you want to go beyond the generics.
Black is a game described to be basically Gun Porn. Even That Other Wiki redirects "Gun Porn" to it. In fact, that was the unofficial tagline for a while (not to mention copiously used by the developers in interviews). The menu background for the game consists of slow-motion shots rotating around highly detailed gun models in all possible directions, often throwing in the guns firing in order to really seal the deal.
Ghost Recon takes it to the next level with the "Gunsmith" in Future Soldier - literally anything can be modified on a gun, from the trigger, to the gas system, to the barrel length, to the ammo, and more. There's even an online version of Gunsmith to put weapons together how you'd like.
Operation Flashpoint features a ton of modern military small arms and ammo variants, but due to the game engine not supporting modular attachments, a lot of the weapons are just variants of the same basic weapon with different accessory configurations. For example, M4A1 with iron sights, M4A1 SD (suppressed + iron sights), M4A1 CCO SD (suppressed + red dot sight, M4A1 M203 (underbarrel grenade launcher)...
And what the last example lacks in modularity, Brink makes up for it. Customization screens allow for an intimate rendering of the dozens of weapons you can modify. Weapons which you can attach on up to 4 or 5 different areas. Sights, silencers, extended or drum mags, bayonets...the list goes on.
The Metal Gear series, while in-game doesn't feature a lot of gun action, in-game cutscenes (especially in the GameCube remake of MGS) make it one. And throw in the detailed descriptions of guns (to varying accuracy) as well.
Naked Snake is a bit of a gun pornographer himself. The way he describes the M1911A1 he gets from EVA early on his mission sounds exactly the way car enthusiasts talk about their rides. Seriously, he sounds more excited about the gun than he is about the hot, Absolute Cleavage baring woman who's trying to seduce him. Played for Laughs in the special features, where it's a lighter that EVA uses when he pulls the trigger. Snake's face is PRICELESS.
Max Payne has a bit of this as well. The games even do "bullet cams" for the sniper rifle. Some of the mods really make the game into a gun porn game.
All of the weapons in the Resident Evil remake for GameCube have a gun porn section in it, complete with firing action for some of them.
Resident Evil 5 has a bit of firearm fetish going for it. The game uses a lot of correct names for weapons (averting A.K.A.-47) and you're offered new guns for making your current firearm as powerful as possible. In general the game has a lot more variety to its weapon selection than previous RE games as well.
The Nerf N-Strike game is basically this... with Nerf guns. Its sequel included actual customization options, some new guns, and the removal of the duplicate guns that the first one was plagued with.
The Hitman games let you collect a large variety of weapons, and then usually hand you a nice firing range to test them out on.
This trope seems to be why Unreal Tournament III contains guns that look like exploded-view models of the actual weapons they're supposed to represent. Lots of totally hawt levers exposed in those babies.
Borderlands. The game's debug menu lists over 3 million guns, and the devs stopped counting after they reached 17 million guns.
There's a glitch in the Mad Moxxi expansion that can result in what one poster◊ described as "some kind of homicidal Scrooge McDuck wet dream". If you haven't played the game, just know that each one of those thin points of light is sticking out of its own gun.
Taken Up to Eleven by Borderlands 2, where every manufacturer now have their own distinctive style not only limited to color scheme and different grips.
There's only one gun in the Team Fortress 2's "Meet the Heavy" video, but the Heavy's rhapsodic description of it certainly qualifies.
"I am Heavy Weapons Guy, and this is my weapon. She weighs 150 kilograms and fires 200-dollar custom-tooled cartridges at a rate of 10,000 rounds per minute. It costs 400,000 dollars to fire this weapon, for 12 seconds!"
STALKER already has a fairly large and varied collection of guns in the basic configuration, but the Arsenal Mod for Shadow of Chernobyl really seals the deal, with more than 60 new guns to play with. Search deeper in the net and many (usally Russian) compilation mods, for example, "StalkerSoup", go into triple digits. Not only are they functional, but each gun tends to have paragraphs worth of info and history in the inventory.
Then there's the M.S.U. mod, aka MasSiv Update, for Call of Pripyat, which is the game's version of the Arsenal mod, except with 80 plus guns as well as a major graphics overhaul and a patch that fixed a huge amount of bugs and glitches that plagued the game, especially when it was modded.
Jagged Alliance 2. With the v1.13 mod, they have every gun in the Cool Guns section except for seven(AR-18, BAR, M1887, MP 40, MG 42, TEC-9, and Mauser C96, to be exact), and nearly all the guns in the Rare Guns page. There are many variants on individual guns, as well, leading to around 300 guns.
As if that weren't enough, there's multiple variants of ammunition for the same caliber, and a multitude of parts to use to customize individual guns with. There's so much gun porn it's quite easy to get distracted from actually fighting in favor of pimping out your mercenaries with the coolest guns possible.
As a spiritual successor, Brigade 7.62mm fits this trope too. In 3D! Moreso with the fanmade mods.
Fallout: New Vegas has a faction called the Boomers, who practically have a Cargo Cult-esque religion based around guns and explosives. Naturally, the main character can earn some serious Messiah points by salvaging a pre-War B-29 from the bottom of Lake Mead for them.
The Gun Runners are at comparable levels of Gun Porn, though their outlook is secular and their plot relevance is much smaller.
The biggest example of gun porn in the game would be the sheer amount of things you can do with firearms: along with modifying them, you can also reload your own ammunition. A big part of getting the most out of your weapon for the lowest cost is breaking down ammo you don't want or need for the lead, gunpowder, and primers and using them to craft ammo types like hollow points (more damage, less armor penetration) and armor piercing ammo (vice versa). Even energy weapons get in on this, letting you recycle energy cells and make overcharged ammo that wears the guns out faster in exchange for better performance. You can even find weak ammunition (like .38 Special for .357 Magnum weapons or .223 for 5.56x45mm guns) that puts less wear on the gun and is often cheaper. A major part of the modding scene is adding even more craftable ammo types and even letting you recycle the brass casings to reform them into new calibers.
In the game Conkers Bad Fur Day, play this trope parodying Matrix when Conker blackmail the programmer to help him in killing Heinrich.
Battlefield 3 has an absolutely huge wealth of guns for you to use in the multiplayer, as well as many scopes and attachments for your pleasure.
Receiver doesn't have a lot of guns (three as of the RC6 update), but the gun mechanics are insanely detailed. We're talking "check the safety, cock the hammer, and reload individual bullets into the magazine"-level detailed.
For those wanting to create a Frankenstein's monster equivalent of a gun, you're in luck! Pimp My Gun and Pimp My Airsoft let you mix and match gun parts of popular firearms to create the dream weapon you want. So I'll take the AK's receiver, add the HK 416's handguard, maybe throw in an M203...
There is also a jewish character who basically hoards guns in his basement, including a M1919 .30cal machinegun, partly hidden behind an israeli flag. He also talks to the main character in a very endearing way about them.
The Transformers' god, Primus. He's the size of a planet, (because he IS one), and he is slagging MADE OF DAKKA. ENORMOUS shoulder cannons. Huge twin wrist guns. Banks of guns and missile launchers in his shins and lots of other places. (And when that's not enough, he can use his moons as Epic Flails.
Three magic words for Heckler & Koch fans: The Grey Room◊. Currently housed in HK’s Virginia facility, The Grey Room is a unique collection of HK weapons, particularly appealing to the gun porn aficionados thanks to the large number of rare and prototype weapons such as the G11 and XM8.
Dragon*Con 2010 (a Sci-Fi/media convention) had an entire room, appropriately called The Armory, set up with loads of weapons on display, from pistols to heavy machine guns... and beyond.
