->''"They say that in the army''\\
''The guns are mighty fine''\\
''But when you pull the trigger''\\
''The bullets fly behind!"''
-->-- "They Say That In The Army''

This is a comedy weapon trope (although there are dramatic examples) featuring a gun designed or modified to fire backwards, tricking the person who uses it into shooting themselves. A common version seen in cartoons is to bend the barrel back into a "U" shape. Note that this trope may still come into play even if the person who might fire the gun would have to be really stupid not to notice the modification.

These guns tend to show up in cartoons and spy genre {{pastiche}}s.

Despite the trope title, other projectile weapons, such as a crossbow or [[http://en.wikipedia.org/wiki/Hwacha hwacha]], may be examples of this trope.

* ''VisualNovel/UminekoWhenTheyCry'': Battler suggests this to explain one crime.
* ''Manga/OnePiece'': The anime only G8 arc had the Straw Hats (specifically Luffy, Ussop, Zoro and Robin) when the Marines corner them in a storage vault (They had raided it to recover the treasure they had gained from Skypeia). When a Marine Commander named Shepherd pulls out a gigantic gun dubbed the "Eagle Launcher" and goes to aim. But the Marines around him tell him he's pointing it the wrong way. When he doesn't believe them, he fires and predictably ends up hitting the troops behind him. What's more Robin uses her Hana Hana powers to take control of him and the gun to keep firing it, giving the Straw Hats a path to escape.
* One story in the original ''Manga/LupinTheThird'' manga had Lupin himself being shot in the head by a gun that fired backwards, [[EarlyInstallmentWeirdness set up by Jigen no less]]. [[NegativeContinuity He gets better]].
** A less fatal variation appeared in the TV Special ''Anime/LupinIIIEpisode0FirstContact'' where a mob boss tried to shoot Lupin with his own gun...only for a [[ExtendoBoxingGlove coiled boxing glove]] to fly out of the other end.

[[folder:Comic Books]]
* A Franco-Belgian comic book involving a zombie problem features semi-automatic pistols tricked out to fire their sliding barrel backwards, killing the user.
* ''ComicStrip/SpyVsSpy'': As seen in the page image, this occurs in one strip drawn for a series of paperbacks.
* An issue of the ''[[Franchise/TheFlash Impulse]]'' comic book guest-starring The Riddler featured said Crown Prince of Conundrums with a revolver rigged to shoot backward.
* Used seriously in one ''ComicBook/{{Torpedo}}'' story, where the killer commissions a special one-shot gun for this purpose, replacing a cop's gun with it.
* In the ''ComicBook/StanleyAndHisMonster'' mini-series, Ambrose Bierce gives Stanley a backwards-firing water pistol that squirts him in the face. (A bit more serious than it sounds -- Bierce is trying to figure out who in the house might be a demon in disguise, and so the gun shoots ''holy'' water -- but since Stanley's just a kid, he's okay if wet. The actual demoness who shows up a bit later [[spoiler:to fetch the same demon Bierce is after back into Hell]] and ends up getting her own hands on the pistol and pulling the trigger is somewhat less amused.)
* ''ComicBook/SinCity: The Big Fat Kill'' had this happen to [[DirtyCop Jackie Boy]]. Miho puts a throwing spike into the barrel of Jackie Boy's gun. Despite Dwight's warnings not to fire the thing, he fires the weapon, and the slide flies backwards, impaling him through the head. This doesn't even kill him, just render him blind.
* ''ComicBook/{{Urbanus}}'': In "De dochter van Urbanus", there are three of them.

[[folder:Comic Strips]]
* ''ComicStrip/FoxTrot'' did this with a squirt gun in one strip.

[[folder:Films -- Live-Action]]
* Happens with a wrongly assembled cannon in Creator/BusterKeaton's ''Film/ThePlayhouse''.
* In the 1966 film ''Film/TheSilencers'' (part of the MattHelm series starring Music/DeanMartin, a parody of the spy genre), a guard got hold of one of these guns, not knowing it was a trick gun, and pointed it at a woman - as she stoically awaited her fate (she didn't know what it was either). The guard pulled the trigger, shot himself, looked kind of puzzled, and shot himself ''again''. She took the gun and fled. When she was later confronted by another guard, she pointed it at her own chest. The guard, thinking she was about to commit suicide, said "You don't have to do that." She replied "I must" and pulled the trigger, killing him.
* In ''Film/CasinoRoyale1967'', GeorgeRaft, who was best known for playing gangsters, is shot with such a gun.
* In ''Film/BallisticEcksVsSever'' the big bad tricks a lackey into killing himself by giving him a backwards firing pistol. More of a loyalty test with a built in punishment, since he was told to shoot himself with it.
* In the 1989 Tamil film ''ApoorvaSagodharargal'', the dwarf Appu tricks Sathyamoorthy into killing himself with a circus hand gun that shoots backwards.
* One of these shows up in ''Film/TheAmerican'' when [[spoiler: George Cloony's character intentionally designs one for an assassin. Why would he do this? Simple: He figured out that the assassin would use the gun to kill him.]]
* An alternate ending for ''Film/DieHardWithAVengeance'' has John [=McClane=] threatening Simon Gruber with a Chinese rocket launcher with the sights removed, allowing Gruber to point the rocket whichever way he liked. [[spoiler: Gruber ultimately points the rocket launcher the wrong way.]]
* ''Film/LawAbidingCitizen''. A criminal is about to execute a policeman whose gun he stole, only for the 'cop' to reveal he's [[ImpersonatingAnOfficer actually the man whose family he murdered ten years ago]]. Pulling the trigger releases needles in the grip injecting the criminal with a paralysing neurotoxin, so he can be tortured to death at leisure.
* One of the victims on ''Film/{{Mindhunters}}'' is killed by sabotaging his gun this way [[ChekhovsGun after he spends the entire movie complaining that he doesn't want to part with his gun]].
* An improvised version occurs during a GunStruggle in ''Film/{{The Art of War}}'' (2000), with the protagonist jamming the barrel of TheDragon's pistol against a marble floor and forcing him to fire, causing part of the slide to fly back into his face from the confined gunshot.
* The titular pistol in ''Film/TheMexican'' killed its first victim this way when it was being test fired. This lead to the persistent rumor that the pistol was cursed.
* ''Film/{{Hulk}}''. The Incredible Hulk bends back a tank's cannon so it's pointing at the wide-eyed crew. It can't fire this way of course, [[YouWouldntLikeMeWhenImAngry but they get the point]].

* The ''Literature/{{Lovejoy}}'' novel ''The Judas Pair'' featured a pair of duelling pistols designed to fire backwards. The owner would challenge someone to a duel and let them fire first. His opponent would end up shooting himself in the face. This story was also made into an episode of the ''Lovejoy'' TV series.
* The ''Literature/{{Clue}}'' book "Midnight Phone Calls" has a chapter titled "The Guest Who Couldn't Shoot Straight". While hunting an escaped rhinoceros, the six guests are armed with revolvers, two that only shoot to the left, two that only shoot to the right, and two that work normally. At the end, one of the first four revolvers is pointed directly at the rhino, but apparently hits one of the other guests instead. (As usual, it turns out the "victim" isn't really dead.)

* The [[http://livre.fnac.com/a2516355/Hugh-Laurie-Tout-est-sous-controle French Cover]] of Creator/HughLaurie's ''Literature/TheGunSeller'' shows an automatic pistol with the barrel clearly pointing backwards.

[[folder:Live-Action TV]]
* In "The Girl Who Was Death", a zany [[{{Pastiche}} spy-spoof]] episode of ''Series/ThePrisoner'' (original), Number 6 modifies some rifles so they'll fire backwards before some guards arrive and attempt to shoot him with them. He also modifies German "potato-masher" grenades so the charges are in the handles instead of the heads.
* In an episode of ''Series/TheWildWildWest'', Miguelito Loveless hands James West such a pistol, but he sees through the ruse.
** Said gun pulls a [[ChekhovsGun Chekhov]] at the end of the episode, when Loveless pulls a gun on a hostage, only for West to remind him that there were two identical-looking guns in the bag, only one of which shot forwards.
* Happened in ''Series/TheBennyHillShow'' episode "The B-Team", a skit that spoofed ''Series/TheATeam''.
* ''Series/TheManFromUNCLE'' had in one episode a pistol which fired backwards AND forwards, so that the assassin would take out her target and at the same time inadvertently silence herself for good.
* In a season 3 episode of the Canadian series ''Series/TheListener'', this turns out to be the payoff for the villain's EvilPlan to wreak revenge on the guy who molested his daughter -- he set up a scenario where he knew the guy would get the gun from him, but the gun was rigged to shoot the chamber backwards right into his head. This also allows him to rationalize the guy's death with his personal vow against killing others; ''technically'' he didn't pull the trigger.
* Happens to Kenny in ''Series/MyNameIsEarl'', only with mace, while trying to spray Earl with it. Earl helps take the sting out of his eyes afterwards.
--> '''Earl''': When you steal a lot of purses, you learn a thing or two about mace.

Later Seska forces Tuvok to PutDownYourGunAndStepAway, but the same thing happens to her as Tuvok sabotaged his rifle before handing it over.
* The bent-barrel version of this trope was tested--and [[JustForFun/TropesExaminedByTheMythBusters confirmed]]--on ''Series/MythBusters''.
* ''Series/FatherBrown'': In "The Lair of the Libertines", one VictimOfTheWeek is killed when the killer removes the safety catch from his pistol. This causes the firing pin to shoot out backwards when he fires the pistol, hitting him between the eyes.
* ''Series/RedDwarf'': In "The Inquisitor", Kryten and Lister steal the Inquisitor's gauntlet and Kryten reprograms it. When the Inquisitor reacquires it and fires it at Lister, it fires backwards and removes the Inquisitor from history.
* ''Series/InspectorGeorgeGently'': At the end of "Son of a Gun", the skinhead leader Jonjo Burden is blinded when the Sten gun he is aiming at Gently backfires. It turns out the boy he was forcing into modifying it hadn't finished boring out the barrel.
* ''Series/TheGoodies''. In the movies episode, Graham Garden is making TheWestern. He kicks open a door holding revolvers GunsAkimbo, only for the door to slam back in his face. When he opens the door again, both barrels are bent upwards, causing debris to rain down from the ceiling when he fires.
* In a Russ Abbot sketch parodying ''Film/TheGodfather'', the [[ParodyName Oddfather]] explains that if he suspects someone's trying to kill him, he leaves a backwards-firing gun on the table, so the would-be assassin snatches it up, aims it at him, and shoots themselves. The henchman he's explaining this to grabs the nearest gun, shouts "[[TemptingFate I'm smarter than da rest! Say goodbye, Oddfather!]]", [[TooDumbToLive points it at himself, and pulls the trigger.]] Turns out it wasn't a backward-firing gun after all.
* "Wine, Women and War", the second pilot for ''Series/TheSixMillionDollarMan'' has Steve Austin crimp the barrel of a mook's gun closed with his bionic fingers. The mook doesn't notice this and, despite Austin warning him not to fire, he shoots and nails himself (though it's unclear whether he actually shoots himself or gets knocked out by backfire).

* In the BBC radio drama ''Franchise/{{Batman}}: The Lazarus Syndrome'', Ra's al Ghul accidentally shoots himself when he grabs a gun from Batman's trophy room, not realising that it is a booby-trapped weapon rigged to fire backwards.

[[folder:Tabletop Games]]
* ''TabletopGame/GrimtoothsTraps Too'' contains a reverse-firing "Double Crossbow" as a loot trap.
* One ''TabletopGame/{{Paranoia}}'' mission includes an experimental weapon that needs to be field-tested. When activated, it explodes. [[spoiler:This is intentional. The weapon is called the "Traitor Killer"; it's assumed that there'll be a traitor on the team, and that they'll volunteer in hopes of not being targeted.]]
* The classic TabletopGame/DungeonsAndDragons module ''Expedition to the Barrier Peaks'' has a super-science pistol that relies on a player to interpret it being held like a normal gun (something the ''characters'' should never have seen before) to apply this effect. It doesn't actually fire backwards - its designed to fire at what its aimed at, its just designed to fool the ''player'' using meta-game knowledge instead of figuring out the correct way to hold it.

[[folder:Video Games]]
* ''VideoGame/CobraTriangle'': One of the two forms of the top of the Fire power-up chain fires one bullet from the fore, one from the aft, and one each starboard and port.
* One of the ''VideoGame/TalesOfMonkeyIsland'' chapters has Guybrush insert a glass tube in the [[VisualPun shape of the letter 'U']] into an antagonist's gun, causing it to fire backwards.
* The site ''Epic Mafia'', centered around an online version of the [[ParlorGames parlor game]] ''Mafia'', has the Fabricator role. While Village-aligned roles such as the Gunsmith, Blacksmith, and Santa can secretly give others gifts every night, this EvilCounterpart can create fake versions of items. This includes a fake gun which backfires and kills the user.
* ''VideoGame/DuckGame'' has one inspired by the Suicide Gun image manipulation. [[TooDumbToLive Naturally, using it kills its user]] and it's often hard to tell from the normal revolver due to the small size of the handle and trigger.
* [[spoiler:The Gun that can Kill the Past]] in ''VideoGame/EnterTheGungeon''.
* In ''Videogame/WarThunder'', damage to the breach of the tank's cannon can cause it to misfire. Attempting to fire with a damaged breach has a fairly high chance of causing the shell to explode in the breach, instantly killing the crew.

[[folder:Web Original]]
* In one episode of ''Literature/BastardOperatorFromHell'', we find out that the cattle prods have two settings. "Stir Fry" operates normally, while "Stun" causes the high voltage to fry the person brandishing the device. This is then used by the Bastard when he suggests the Boss use the cattle prod to stun the PFY.

[[folder:Western Animation]]
* Occurs in numerous ''WesternAnimation/LooneyTunes'' shorts.
** Apparently you can make any gun fire backwards if you stick your finger in the barrel. (As the Series/MythBusters proved, [[JustForFun/TropesExaminedByTheMythBusters this doesn't work in real life]].)
** In one notable example, WesternAnimation/BugsBunny causes Wile E. Coyote to shoot himself, several times, simply by moving the sight to the other end, or removing it completely so he can't tell which end is which.
** And in "WesternAnimation/HillbillyHare", he does it by turning the barrel of a long rifle round after the trigger has been pulled.
** A ''Series/{{Farscape}}'' episode in which Crichton [[AndYouWereThere imagines himself]] in a ''WesternAnimation/LooneyTunes'' cartoon has him pulling this trick by sliding the sight forwards on D'Argo's shotgun. An angry D'Argo swaps the barrel round, only to shoot himself a second time. Exactly like Wile E Coyote above.
* ''[[ComicStrip/DennisTheMenaceUK Dennis and Gnasher]]'': In "Yard Sale", Walter picks up Dennis's squirt gun and attempts to shoot Dennis with it, only for it to spray him in the face as Dennis says it backfires. He then turns the gun around and attempts to shoot Dennis again, only to soaked again as the water comes out the barrel and Dennis adds "Sometimes".
* Used in the ''WesternAnimation/{{Futurama}}'' episode "Assie Come Home" when making a delivery Leela has Bender bend the barrels of all the guns leading to all the gang members killing themselves.
* In one episode of ''WesternAnimation/TheSimpsons'', Mr. Burns moves the power plant to India. When one of Moe's patrons comments that the bar is being powered by imported electricity, Moe sees no problem and points out other imported stuff. When he's asked if he has anything made in America, he shows his shotgun and tries to shoot, causing it to backfire.
* ''WesternAnimation/Ben10Omniverse'': In "An American Benwolf in London", a robot grabs Rook's gun off him and points it at him. Rook says that he knows something about the weapon that the robot does not. As the robot fires and blows a hole in its own chest, Rook says "You're holding it backwards".
* ''WesternAnimation/MenInBlackTheSeries'': When facing off against an escaped alien prisoner in "The Take No Prisoners Syndrome", J grabs an unfamiliar alien weapon from the armory and threatens him with it. The Bug sneeringly informs J that he's grabbed a "Sonar Tube" and is holding it backwards. J turns it around, looking at the brace-like structure on the end he's pointing at himself, then points it back at the Bug and pulls the trigger. A small nozzle promptly pops up and aims a targeting laser at J's forehead, forcing him to jerk the blaster up before it nearly takes his head off.

[[folder:Real Life]]
* A poorly-made, incorrectly assembled or worn-out firearm or excessively powerful cartridge loads can cause the bolt, part of the breech or -- in the case of semi-automatic pistols -- the slide to be blown back into the user's face. The ReliablyUnreliableGuns page has a couple of examples.
** The most notable version is probably the Ross Rifle, a Canadian-designed and built substitute for the excellent Lee-Enfield during UsefulNotes/WorldWarI. While a fine design, just as powerful and slightly more accurate, it could be disassembled and then reassembled with the bolt head turned in the wrong direction, chambering and firing a round without the bolt securely locked to the receiver, resulting in possible EyeScream.
** The US UsefulNotes/NavySeals are among the only members of the US military to use a 9mm pistol that ''isn't'' the Beretta M9, partly because of a defect that caused the same sort of issue as the Ross rifle above -- a specific part was giving out five times earlier than it should have, causing the slide to fly off and hit the SEAL firing it in the face while training. As the quote went, "you ain't a SEAL until you've eaten Italian steel".
*** Beretta eventually fixed the problem with the M9 (hence the model now called "[=M9A1=]", the "A1" bit meaning it went through an alteration) and the only reason the [=SEALs=] encountered it was because they train in a month more than most members do in their entire careers. [[NeverLiveItDown However, the damage was already done]].
* In UsefulNotes/WorldWarI there were attempts made to mount large caliber cannons onto the flimsy biplanes of the day to shoot down zeppelins, and one method used to mitigate the substantial recoil was to simply weld a second cannon facing backwards to the back of the forward firing cannon, and firing both guns at the same time, the rear one loaded with chain or other such material to cancel out the recoil of the forward firing gun.
* [[https://en.wikipedia.org/wiki/Recoilless_rifle Recoilless rifles]] were adopted after UsefulNotes/WorldWarI to combat tanks. Instead of the weapon itself taking the hit from the cartridge being fired, a lot of the gas is vented from the back. The same principle is used by rocket launchers like the bazooka and RPG-7. Because the blast isn't contained, the weapon itself is much lighter, allowing small vehicles and individual soldiers to carry a weapon that can penetrate tank armor. The backwards firing part comes in when you consider that those same gasses that aren't stopped by the weapon and kill anybody some feet behind it, this also prevents them from being fired indoors, nearby walls would bounce the gasses back to the shooter.
** During the Korean War, a number of U.S.-built recoilless rifles were captured by Chinese troops, who attempted to use them without being aware of how they operated. They didn't do it twice.
* Water guns have been made so that there's a rotating exit on the top allowing guns to squirt in any direction and forward at the same time.
* There is a possibly photoshopped image of a backwards revolver circling the Internet. ''WebAnimation/ExtraCredits'' has used it a few times as one of its BRollRebus-esque images.
* Backwards-firing [[http://www.douglas-self.com/MUSEUM/COMMS/cutlery/cutlery.htm Combat Cutlery]]. "It is difficult to imagine a social gathering where it is appropriate to shoot off your own elbows."
* One 'dirty trick' of covert warfare is to arrange for your enemy to get hold of ammunition loaded with C4 instead of gunpowder.
