->'''Gemini:''' Here, let me give you a hand.\\
'''Kim Possible:''' How often have you used that line?
-->-- ''WesternAnimation/KimPossible''

Various parts of the body have been weaponized in fiction and the fingers are no exception despite their small size. Aside from RuleOfCool, the two most common reasons given for this setup are '''increased firepower''' and '''concealment'''.

[[foldercontrol]]

[[folder:Firepower]]
Fingers weaponized for '''firepower''' are usually a specific variation of the ArmCannon which involves placing a ranged weapon in every finger and occasionally the thumb as well. Smaller machines may have all fingers linked to a common magazine or ammo management system while larger units can have a separate system in the same finger as its gun. There are also cases where the fingers are merely barrels.

This layout is more often used in '[[MightyGlacier raw power]]' machines to indicate their destructive ability. The implication is that the unit has [[MoreDakka many times the firepower of a grunt's main weapon]]- by having eight or ten of that weapon in its hands alone.

The primary claimed benefit of this design is that it offers MoreDakka without sacrificing finger articulation. This ignores the fact that flexible or folding barrels would severely reduce the durability of the guns. Proposed workarounds include housing the entire weapon system in the finger''tips'', reducing the power of the weapons, making all the fingers rigid rather than articulated or having articulated fingers that go rigid before firing- all of which sacrifice either hand or weapon functionality. In the end, RuleOfCool is the only proper justification.

Pay special attention to the fingers of a HumongousMecha if they appear to be flexible hollow tubes or if they sport openings or lenses at the ends because these indicate guns. 'Mittens' with rows of barrels are sometimes used by designers who want to mix things up, though these are even less practical as they lose all but the most basic hand functions. Some less humanoid designs may have hand-mounted guns that double as fingers rather than fingers with guns inside, usually in cases where the machine has fewer than five fingers on each hand.
[[/folder]]

[[folder:Concealment]]
'''Concealed''' finger guns can be made virtually indistinguishable from unarmed fingers, particularly if the user's unarmed fingers also look mechanical. Any gun parts that appear on security scans can be handwaved as part of the hand's mechanisms ([[FromACertainPointOfView which they are]]). Mechanical or mechanically augmented characters who have not previously been shown with weapons can be revealed to sport these without stretching WillingSuspensionOfDisbelief.

Apart from the design difficulties listed in the '''firepower''' section, concealed finger guns also need an even greater degree of miniaturization or integration with the rest of the hand to keep them from being detected, placing further limits on their functionality. Cruder designs that impede the function of the fingers to allow greater power also make detection easier. Finally, risk of detection by internal scans complicates the inclusion of any built-in magazine as most ammunition has a distinctive appearance, limiting the guns to a small number of shots per weapon if solid rounds are needed.

Due to all these limitations, concealed finger guns are usually used for assassination or self defense. However, HumongousMecha may make effective use of this design by concealing ''anti-personnel'' weapons in their fingers- these may not be effective on other large machines but are enough for infantry and light vehicles or aircraft.

'''NOTE:''' Guns installed in the metacarpal region (i.e. behind the base of the finger or even further back) should go under ArmCannon, PowerPalms or HandBlast instead. For the gesture involving making a gun with one's fingers, see FingerGun. The use of said gesture to channel magic or psionics belongs there as well. Stuffing the finger in a gun is FingerInABarrel.

!Examples:

!!Firepower:

[[folder:Anime & Manga]]
* 004 from ''Manga/Cyborg009'' has finger machine guns as part of his arsenal.
* ''Manga/GiantRobo'' has missile launchers in its fingers.
* ''Anime/GunBuster'' fires its Buster Missiles from its fingertips.
** Several machines from the sequel ''Anime/{{Diebuster}}'' have finger guns as well.
* The Moskas in ''Manga/KatekyoHitmanReborn'' fire out of their fingers and Mini Moska fires popcorn out of his fingers.
* ''Anime/MazingerZ'':
** In episode 10, Mazinger-Z shows he can shoot missiles from its fingers. That weapon is never used again, though (surely because the animators realized [[AwesomeButImpractical how silly and dangerous was storing missiles]] into a RocketPunch).
** Several [[{{Robeast}} Mechanical Beasts]] are armed with this weapon (for example, Danchel in one of the earlier episodes. Or one Beast from the ''Mazinger-Z vs Devilman'' feature).
* Since the Zeong from ''Anime/MobileSuitGundam'', ''Franchise/{{Gundam}}'' series have occasionally put beam guns in the fingers of enemies they want to make especially threatening. The earlier Gouf from the same series had machine gun fingers.
* One of Blackbeard's henchmen in ''Manga/OnePiece'' has these.
* ''Anime/RobotRomanceTrilogy'':
** ''Anime/CombattlerV'''s Rock Fighter.
** ''Anime/VoltesV'''s Finger Missiles.
* Among many other armaments, the cyborg Grey the Ninelives had machine guns in each of his fingers in the anime of ''Manga/{{Trigun}}''. For contrast, the protagonist Vash has an ArmCannon.
* Wing Saber from ''Anime/TransformersCybertron'' Transforms into some sort of Attack Plane, with his hands transforming from the miniguns mounted on it's wings, he's perfectly capable of using them as miniguns in his robot mode as well.
* This is Franklin's signature ability in ''Manga/HunterXHunter''. Justified in that the fingers themselves are fully biological and functional, but what he's shooting are {{Ki Attack}}s. They still fall under this trope, however, as his stance and hand gestures when he shoots, and the damage and destruction they inflict, are as if he's wielding ten miniature machine guns.
* ''Manga/{{Naruto}}'': Kimimaro, with his power to remove and regenerate his bones, is capable of [[BallisticBone shooting his fingertips at enemies like bullets]].
[[/folder]]

[[folder:Comic Books]]
* A somewhat obscure Creator/MarvelComics villain named Professor Power fought many heroes using PowerArmor. One version of the armor included guns located in each fingertip of his gauntlets which he used in a fight against SpiderMan and the original members of the ComicBook/XMen.
* The Marvel Comics hero Machine Man is capable of firing .357 Magnum rounds from one of his fingers.
* British comics hero TheSteelClaw had a mechanical right hand, the main benefit of which was that he could become invisible by passing a large electrical current through it (no, me neither). However, it also concealed numerous handy gadgets, including a finger-mounted gun which fired armour-piercing ammunition.
* A one-off villain in an X-Men title was a mutant tattoo artist that could give [[PowerTattoo power granting tattoos]], who had variously empowered an entire gang. One of them had a gun tattoo on his hand and index fingers he could fire with the appropriate gesture.
[[/folder]]

[[folder:Films -- Live-Action]]
* ''Voyage into Space'', being based on the earlier ''Manga/GiantRobo'' manga, features a giant robot whose main armament is missiles he can shoot from his fingertips.
* Ultron in ''Film/AvengersAgeOfUltron'' has finger ''lasers'', understandably as Iron Man was involved on his creation.
[[/folder]]

[[folder:Live-Action TV]]
* ''Franchise/PowerRangers'' / ''Franchise/SuperSentai''
** ''Series/MightyMorphinPowerRangers'' has the Dragonzord launch missiles from its fingertips. Tor did the same thing in season 2.
** The Delta Command Megazord of ''Series/PowerRangersSPD'' does the same with lasers. Its [[Series/TokusouSentaiDekaranger Sentai counterpart]] Dekabase Robo also uses finger-mounted missile launchers.
** In ''Series/PowerRangersJungleFury'', the Rhino Ranger's arm-mounted weapon had laser barrels on one side, looking similar to fingers when that side was used.
** The [[Series/PowerRangersMegaforce Ultimate Legendary Megazord]] got this on one hand, while the other became [[ThisIsADrill a giant, spiral grooved spear]].
* The 1974 incarnation of [[Film/GodzillaVsMechagodzilla Mechagodzilla]] can fire missiles from his fingertips.
* In ''Series/TheAquabatsSuperShow'', Jimmy the Robot has lasers built into his fingers.
* ''Series/DoctorWho'':
** The episode "The Android Invasion" features creepy, radiation suit-clad androids with guns built into their fingertips.
--->"...Is that finger loaded?"
** Similarly, the living-plastic Autons have guns concealed inside half of their hands -- the fingered half drops away on a hinge, revealing the hidden ray-gun.
* In ''Series/LukeCage2016'', Diamondback introduces himself to Cornell Stokes' former crew, who have been dispatched by Shades to look for Luke Cage's body. Diamondback draws out his right hand from his jacket and points it around in the FingerGun gesture. Then he uses said finger to "fire" a round right into one henchman's shoulder. It turns out he'd drawn a real gun with his left hand and fired it from the hip while everyone was distracted, and it's his not-so-subtle way of telling them not to look for Luke Cage in the most obvious places.
[[/folder]]

[[folder:Tabletop Games]]
* ''TabletopGame/{{Shadowrun}}''. Guns in cybernetic fingers were first mentioned in the 2nd Edition ''Cybertechnology'' supplement.
* In ''TabletopGame/Warhammer40000'' Obliterators are infected with a "virus" that turns their whole body into ShapeshifterWeapon. They sometimes manifest this trope (especially older models).
** Some of the more obscure factions (you can find them in the Inquisition codex, for example) of ''[[TabletopGame/{{Warhammer 40000}} 40K]]'' have the Jokaero relics known as digital weapons: miniaturized versions of lasguns, flamers and needleguns that could fitted onto fingers like rings. They also popped up as equipment cards in the SpinOff boardgame ''Space Crusade'' and are an available weapon on the Fantasy Flight Games roleplaying games starting with ''TabletopGame/RogueTrader''.
[[/folder]]

[[folder:Video Games]]
* In ''VideoGame/{{Xenogears}}'', [[MightyGlacier Maria's Seibzehn]] has missile launchers in its fingers.
* The WA-FINGER weapon and its variants in the ''VideoGame/ArmoredCore'' series are multi-barreled machine guns designed to look like hands, probably just to justify the name.
* ''VideoGame/EarthwormJim'' gets to use a multidirectional gun that fires out of the three fingers on his suit's hand. It burns through ammo very quickly, but damn if Jim doesn't look like he's [[IncrediblyLamePun having a blast]] while firing it.
* Aigis from ''Videogame/Persona3'' has machine gun fingers fed by an external drum magazine.
* In ''Videogame/SuperMarioRPG,'' one of Geno's weapons is the Finger Shot, which fires bullets out of each of his fingers.
** In the same game, one of Smithy's [[spoiler:true form's]] attacks involve using these.
* The [[CombiningMecha SRX]] from ''VideoGame/ShinSuperRobotWars'' and any ''VideoGame/SuperRobotWars'' series that feature the SRX Team, due to its fingers being formed from the shoulder cannons of one of its components.
* ''VideoGame/MegaManX'':
** Sigma has these in the manga. After he fires it, he uses the heat residue to scar his eyes.
** Violen from ''VideoGame/MegaManX2'' also sports these.
** ''VideoGame/MegaManZX's'' Serpent also has this.
** In remake VideoGame/MegaManMaverickHunterX'' Vile has 3 sets of weapons, his fingers are one of them (for the Vulcan slot).
* MACE, the HumongousMecha FinalBoss of ''VideoGame/Intrusion2'' has these. It can fire both fireballs and homing missiles from them.
[[/folder]]

!!Concealment

[[folder:Anime & Manga]]
* This is [[spoiler:The Reaper]]'s method of killing in ''Manga/AssassinationClassroom''. His index finger bone is replaced with a low-caliber gun, [[InstantDeathBullet which is used to shoot his victim's aorta, causing the victim's blood to spill out]].
[[/folder]]

[[folder:Films -- Live-Action]]
* The assassin Mr. Igoe in ''Film/{{Innerspace}}'' has a mechanical hand, which in one scene actually fires a bullet from the tip of its index finger - thereby forever one-upping the small child who had pointed his own finger gun at him. (Kid was fine. His balloon wasn't.)
* [[BigBad Yatsu]] possesses one in ''[[Film/TetsuoTheIronMan Tetsuo 2: Body Hammer]]'', [[spoiler:having been turned into a LivingWeapon along with Tomoo by his father]].
[[/folder]]

[[folder:Literature]]
* Foaly armed Commander Root with the concealed variety in ''Literature/ArtemisFowl'' because he couldn't go into a hostage negotiation obviously armed. Foaly mentions that they aren't used often because the concealment is so good that people forget that they're wearing them, resulting in friendly fire incidents. Root 'accidentally' has one that knocks out an annoying coworker later in the book.
* ''Literature/HonorHarrington'' has a gun built into her finger and, from the description, her hand does move into something approximating the traditional finger gun position when she fires it. Of course, her entire arm is an ArtificialLimb, and given that assassins keep trying to kill her throughout the books, this seemed like a [[ProperlyParanoid prudent idea]]. Her [[ElectronicEyes prosthetic eye]] is specially equipped with targeting software to allow her to shoot from the hip as well - although her keen kinesthetic sense may make such aid superfluous. As you may have guessed from the list of prosthetic limbs Honor has, more than a few people have attempted to kill her over the years.
* E.E. Smith's ''Family D'Alembert'' series has family patrician Etienne and his weapon hand. Ostensibly lost in a circus accident (the cover story), it was replaced with something infinitely more useful. The various digits can be retrofitted with mission-specific tools (on one occasion he unscrews his pinkie for use as a grenade), but the index finger is a permanent fixture that contains a small blaster.
* In the Literature/PhoenixForce novels, Yakov Katzenelenbogen has a .22 Magnum zip gun hidden in his artificial hand.
[[/folder]]

[[folder:Live-Action TV]]
* From ''Series/GetSmart'': "Would you believe this finger is a real gun?" They do find it hard to believe, so Max fires the gun in the air to prove otherwise. Unfortunately it's single shot. Max later reveals that it has a ''second'' shot [[RuleOfFunny ... and promptly fires it into the air.]] On one show Max is kidnapped and subjected to a ManchurianAgent treatment -- they have to let him "escape" to avoid suspicion, but he repeatedly misses opportunities handed to him. At one point an agent approaches him, he raises a finger and the agent "surrenders", wise to the old "finger gun" trick. Max insistently points out it's only a finger until the agent walks out in frustration. Max keeps plotting an escape, muttering "Come ''on'', Smart, use that fantastic ''brain'' of yours!"
* At one point in Season 3 of ''Series/AgentsOfShield'', Phil Coulson claims that he has one built into his artificial hand. But since he never uses it, he may have been bluffing. It ''has'' been confirmed that he has an artificial hand with a sensor system built in and another that can create a HardLight shield.
[[/folder]]

[[folder:Music]]
* The cover of several Music/{{Stereolab}} releases (the [=EPs=] ''Super 45'', ''Super Electric'', and ''Stunning Debut Album''; the album ''Peng!''; and the compilations ''Switched On'' and ''Refried Ectoplasm [Switched On Volume 2]'') feature a grinning cartoon man in a collared shirt, with his forefinger replaced by a gun barrel. In all of these he's [[SeanConneryIsAboutToShootYou pointing straight at the audience]], and in ''Peng!'' he's firing.
[[/folder]]

[[folder:Video Games]]
* In Videogame/{{Warframe}}, gunslinger-themed frame Mesa's ultimate ability is to bring out the Peacemakers, pistols normally holstered on her arm by attaching them to her fingers, letting her blast away at any nearby enemies in her sight.
* The Lilim [[SexBot Dorothy]] of VisualNovel/VA11HALLA has these, for self-defense. Even though you see her fingers, it can be difficult to notice, but [[ActionGirl Sei]] points out that her fingertips are bigger than they should be, and [[CouldSayItBut suggests getting smaller caps for the barrels]].
[[/folder]]

[[folder:Western Animation]]
* WesterAnimation/InspectorGadget actually has a laser gun in one of his fingers, but with all the other stuff he has in them it's no surprise that he can't seem to get it out when it would be useful [[RuleOfFunny rather than hilarious]].
* ''WesternAnimation/ThePowerpuffGirls'' [[HumongousMecha DYNAMO]] has finger ''missiles''.
[[/folder]]

[[folder:Real Life]]
* There are novelty guns molded to look like fingers, which if held properly look as if the wielder is pointing with his or her own index finger. Technology does exist to integrate firearms into the fingers of prosthetic hands but the possibility does not seem to have been explored as the hands themselves are still being perfected.
