Cool Guns/Shotguns

Winchester M1887 A lever action shotgun, designed by John M. Browning for Winchester. Most sportsmen prefer pump-action shotguns for better action speeds, but that doesn't stop most Hollywood heroes from spinning around sawed-off versions trying to pull a John Wayne.
 * Cool Action: Spin-cocking requires the stock and barrel to be sawed off, after which the gun can be cocked for another shot by spinning it around the fingers in the lower part of the lever. There is a strong potential for accidentally discharging the weapon or breaking your fingers and / or jaw, which is why this isn't so popular in real life as it is in movies.
 * A genuine 10-gauge 1887 was infamously used in Terminator 2 with Arnold himself spinning it in his hand like a toy. In fact, three 1887s were used in the movie, one lightened and with a longer lever; Schwarzenegger is said to have picked up the wrong one at one point and almost broken his fingers trying to spin it.
 * This is replicated on the Winchester 1887 in the Korean online FPS Alliance of Valiant Arms.
 * The Scout's primary weapon in Team Fortress 2, albeit a sawed-off, double-barreled, drum-fed version.
 * The Model 1887 turns up in Modern Warfare 2, though a large number of players wish it hadn't.
 * It shows up in The Darkness II towards the end of the single player and multiplayer co-op mode.
 * Seen in Fallout: New Vegas in an incorrect 20 gauge.

Izhmash Saiga-12

A Russian 12-gauge gas-operated semi-auto, the Saiga-12 is based on the AK layout. Using a 5 or 8-round detachable box magazine, it is regarded as reliable and effective while being a lot cheaper than many competing semi-auto shotguns, and is widely used by Russian security services; it's also proven popular with hunters. Older versions have some unfortunate design holdovers from their AK origins that make the weapon rather difficult to actually load; newer versions address this.
 * "Vera" is probably the most well-known example in media; Jayne's "Callahan Fullbore Auto-Lock" in Firefly was a modified Saiga-12 originally built for the movie Showtime.
 * One with a large 20-round drum magazine and no stock appears in the movie Gamer.
 * Available to buy in Metal Gear Solid 4: Guns of the Patriots; it's the best shotgun in the game, easily overshadowing the others.
 * The 12K version is used by the MEC Engineer class in Battlefield 2.
 * The same version appears in Arm A II.
 * Available in 7.62 High Calibre, with both 5 and 8 round box magazines available. Most prominently used by the rebels, often with double-taped magazines.
 * Gets a lot of screen time on Sons of Guns, one episode even had the guys stick three of them together to make a Gatling shotgun.

Daewoo USAS-12 A fully automatic 12-gauge shotgun designed by the Gilbert Equipment Company and manufactured in South Korea by Daewoo, the USAS-12 resembles a giant AR15-type rifle, weighing over twice as much as an M4. While civilian versions are semi-auto only, military and police versions of this piece of heavy machinery can fire at up to 450 rpm; more impressively, they can do this with standard shotgun shells, while most similar designs require brass casings to reduce the risk of melted plastic fouling the action. While it usually takes a standard 10-round box magazine, it's typically depicted with its 20-round drum magazine. Tends to show up instead of a Jackhammer if the production isn't into Rare Guns.
 * The Rainbow Six series has this weapon in its arsenal since the third game.
 * Also present in Soldier of Fortune 2 where the results were gruesome.
 * Used early on in Stargate SG-1.
 * Modern Warfare 3
 * Battlefield 3, commonly found in the Kaffarov level, as well as an available multiplayer all class unlock, for balance reason, the magazine capacity is reduced to 7, though the extended mag attachment is available. Users are still often frowned and looked down upon.
 * Top-tier shotgun in Far Cry 2, seen with a 20-round drum magazine even though it only has 12 shots.
 * In the Gunsmith Cats manga, one of Goldie's henchmen uses a USAS-12 to wreck the engine of Rally's beloved Cobra during a high-speed chase. This earns Rally's wrath.
 * Appears towards the end of Syphon Filter 2, of special note is the final boss fight where you have to use one to knock
 * One with a standard box magazine was used extensively by Steven Seagal throughout the showdown in On Deadly Ground, where it shreds both people and the side of a helicopter with impunity.
 * Riley has one in his brief return to Buffy the Vampire Slayer as a member of a military demon-hunting unit.
 * A very rare and expensive shotgun in 7.62 High Caliber, though still not as rare as the Jackhammer.

Armsel Striker Also known as the Sentinel Arms Co Striker-12, Protecta, Protecta Bulldog, and Cobray/SWD Street Sweeper [and not the DAO-12, ever]. A South African semi-auto 12-gauge shotgun with a revolver magazine, designed for riot control and combat. The Striker variant features a spring-operated "clockwork" drum magazine, while the Protecta variants use a different mechanism and lack the drum's winding key. This gun was banned by the Clinton Administration, which had it reclassified as a Destructive Device. The gun already had been lengthened to the 18 inches necessary to not be classified as a Short Barreled Shotgun, as well as being internally very different from other versions. It even has a smaller magazine capacity than other legal semiautomatic shotguns and needs to be reloaded one shell at a time and manually wound before it will work. The Striker is not very popular, although it is used by South Africa and Israel.
 * Battlestar Galactica. Tom Zarek's men are seen carrying these on Kobol (though it's portrayed as some kind of grenade launcher), and later the marines during the rescue on Caprica.
 * Used by Leon in Resident Evil 4; though called the Striker, it was actually a Protecta. It was also possible to modify it to have a  one hundred shell capacity. An actual Striker is available in Resident Evil 5.
 * Available in Modern Warfare 2 as the Striker, with a variety of sights; for some reason, it's the standard OPFOR shotgun.
 * A Striker-12 is available in Max Payne 2, replacing the previous game's Jackhammer. The game features a fairly common error in depicting guns with fixed cylinder magazines, in that Max is shown reloading by detaching and replacing the entire drum.
 * A Street Sweeper with a sawed-off barrel is available in the first DLC pack for Grand Theft Auto IV. It's not the short-barrel version, since the front sight is in the wrong place.
 * Engineer weapon in Battlefield 2, the origin of the term DAO-12. This isn't the weapon's name, and just refers to the weapon's trigger type and gauge ("double action only, twelve gauge").
 * Also Battlefield 3, appearing with the same name. This time, it has the stock properly unfolded, though the magazine capacity is reduced for balance reason, though the extended mag attachment make it have the proper 12 magazine size.
 * The Protecta shows up in STALKER: Call Of Pripyat called the "Eliminator," and can be fitted with a SUSAT sight.
 * As with the Glock and MAC, the name "Street Sweeper" found it's way into plenty of nineties gangsta rap lyrics.
 * The Striker appears in Desperado as the "biggest Hand Cannon" that Buscemi has ever fucking seen during the first major shootout of the movie.

KAC Masterkey The Masterkey is a 12-gauge pump-action under-barrel accessory shotgun designed to allow a solder to breach doors without having to carry a full-sized shotgun. A shortened version of the Remington M870, it has a shortened barrel and no stock or grip, instead using the rifle's magazine as a grip. While it failed to get the military contract KAC had hoped for, it inspired the M26 MASS which did get selected; the MASS is a bolt-action device fed by a detachable box magazine, rather than the tube magazine of the Masterkey.
 * Billy uses one in Predator.
 * Snake can buy this as an attachment for the M4 Custom from Drebin in Metal Gear Solid 4, or he can sometimes find them as a drop from various PMC troops that use them as standalone weapons with stocks attached. Why they do this rather than use an actual shotgun is not even remotely clear.
 * Featured as an attachment to assault rifles in Call of Duty: Modern Warfare 2 and Black Ops.
 * Can be purchased in 7.62 High Calibre, though the usefulness is debatable (it takes longer to switch to the shotgun than it does it fire a burst from the rifle).

Remington 870 "Wingmaster"

The pump-action shotgun. Developed in '51, the 870 is the most popular pump-action shotgun in civilian and police use; from ordinary sportsmen to the GSG-9. As of '09 Remington has produced and sold a whopping 10 million units and counting. Most pump-action shotguns in fiction are based off the 870 or sawed off in a tac shotgun style because...well, it looks cool. Chinese clones, such as the Norino Hawk and the H&R Pardner Pump are also very common. Due to the ubiquity of the 870, similar slide-action shotguns such as the Mossberg 500 and Ithaca 37 are often misidentified as Remingtons.
 * Cool Action: there are two: first there's the overdramatic one-hand slam-pump a la Sarah Connor from Terminator 2; the second is an exaggerated lift-and-pump a la Jack from Bioshock. You'd probably sprain your wrist in the first while the second looks cool but is inefficient.
 * The sawed-off shotguns of Team Fortress 2 not wielded by the Scout.
 * The first shotgun available in Max Payne, albeit a police model. Packs a wallop, but it's slow to offset.
 * In Puella Magi Madoka Magica, Homura Akemi steals this, along with a Desert Eagle and a sword, from a Yakuza locker room.
 * Available in both the "Sport" version and the "Police" version in 7.62 High Calibre, where the police version includes a folding stock and higher internal capacity.
 * The Hunting Shotgun in Fallout: New Vegas is the Express version, complete with Sarah Connor style pumping done after reloading.
 * Battlefield 3, the first shotgun (and by extent, all-class weapon) to be unlocked in multiplayer, and is the most powerful shotgun in the game with the downside of being pump action.
 * "Deer Hunter," from popular gun forum "The High Road," has created a rather infamous variant known as the Remington 1740; a double-barreled, pump action shotgun made from pinning a lefty 870 and a righty 870 together, removing the stock from one and the grip from another, and linking the pumps. Has to be seen to be believed!
 * Available very early in 7.62 High Caliber by searching a police car in the starting town. Available in a 4-round hunting version, the 7-round Magnum version, and a Magnum Police with a folding stock.

AA-12 The AA-12 (also known as the Auto Assault-12 and formerly the Atchisson Assault Shotgun) is a shotgun designed in the year 1972 by one Maxwell Atchisson. The original design of this weapon served as the basis for many other autoshotgun designs, such as the Daewoo USAS-12, among others. It's barrage of death is fed either from an 8-shell magazine or either a 20-shell or a 32-shell drum magazine. Many YouTube videos and fan commentaries have dubbed it "The Deadliest Shotgun In The World", because of the one trademark that puts it a cut above the other shotguns: It can be combined with FRAG-12 rounds to perform as a multifunction weapon system.
 * G.I. Joe: The Rise of Cobra: Used by Duke.
 * It should be noted, however, that it's depicted as some disgustingly rechambered high-caliber machine gun.
 * Predators: Used by the mercenary Royce. His is outfitted with a Surefire M900 weaponlight-foregrip and one bitchin' camo pattern.
 * The Expendables: Hale Caesar uses one during the latter of the film. His use of the weapon goes hand-in-hand with Big Damn Heroes, Bang, Bang, BANG!, Blown Across the Room, Ludicrous Gibs and Stuff Blowing Up. It's also fitted with an awesome flashlight/lasersight attachment.
 * That same shotgun will fall into Caesar's hand again in The Expendables 2.
 * This gun is so badass that Trench Mauser will be using it as well, come the Expendables 2.
 * Close Quarter Combat
 * 24: It appears in Season 7.
 * Ultimate Weapons
 * Lock 'n Load With R. Lee Ermey
 * Killing Floor: This game is basically Shotguns Are Just Better personified. In this game, the AA-12 is loaded with the 20-shell drum magazine. Needless to say, as long as a buddy can cover your reloads, no zombie will get anywhere near you.
 * The Club: Dubbed "The Enforcer". Loaded with the 20-shell drum magazine - in this game, the gun's range doubles as an Instant Death Radius.
 * Modern Warfare 2: The AA-12 is used by the Russians and Shadow Company. It is fitted with an 8-shell magazine and has a range pathetic enough to embody Short-Range Shotgun. It's rate of fire is also slower in multiplayer than in single-player.
 * Modern Warfare 3: The AA-12 appears again more often in Modern Warfare 3's single-player campaing. It is also the last Shotgun you unlock for Survival Mode, and a usable shotgun in multiplayer. Sadly, the gun retains the laughable range in both game modes, as well as the slower rate of fire in multiplayer. It also poses as a mule for attachments, as it is fitted with a rail mount, a zip-up bag attached to the stock, a practically useless spare shell bandolier, and a Remington 870 MCS shotgun's pump attached to its own foregrip.
 * Grand Theft Auto IV: Available in the Ballad of Gay Tony expansion pack as the "Automatic Shotgun". It is also available as the "Explosive Shotgun", which can be noticed by the fact that it ejects green shells. Needless to say, it is very powerful.
 * Army of Two: Available in the sequel, The 40th Day. At first fed by the 8-shell box magazine. Then later you can purchase 20-shell drums for it.
 * Combat Arms: Featured as the highest-tier shotgun in the game. There's even a "Dominator" version with foregrip and arctic camo paint. Each version features the 20-shell drum magazine.
 * Spec Ops The Line

Winchester Model 1897

Not to be confused with the 1887 above, the 1897 was a pump-action shotgun and a modified version of the 1893 pump-action developed by--who else--John Moses Browning. The shotgun, like many before it, was primarily a sporting and hunting weapon for most of it's life until the onset of World War 1. When America entered the war, they added an iconic vented barrel shroud and a bayonet lug. The weapon was so effective in trench warfare and so terrifying that the Germans considered it's use a war crime and threatened to kill anyone they captured who used it (The Americans responded by stating they would do the same to German prisoners). After the end of the war, the "Trenchgun" continued to see service right into the Second World War, though it was largely replaced by the Winchester Model 1912. Despite this, the 1897 is the more famous and the one most likely to be seen in a WW 2 film/game/show, likely due to it's devastating reputation in WW 1 and it's intimidating appearance. It's a Rare Gun today, especially the Trenchgun variant and is a highly sought-after collectable by both Wild West and World War 1/2 enthusiasts.
 * Cool Action "Slam firing". Because the shotgun's action lacked a trigger disconnector, this meant that all someone had to do was keep the trigger pressed down and pump the action as fast as they could to keep the shotgun firing.
 * Just about any WW 2 game, movie or TV show where a character uses a shotgun, most likely in the "Trenchgun" configuration with the barrel shroud and the bayonet.
 * In the Resident Evil remake, the civilian version makes a rare appearance as the game's shotgun, replacing the 870 from the original.
 * The Mummy 1999: Rick O'Connel uses a Trenchgun in a few futile attempts to (re)kill Imhotep, but has more success with his undead priests.
 * Mayberry's courthouse has one, which Sheriff Andy takes a hold of during the episode "The Big House".
 * Shows up in Indiana Jones and the Kingdom of the Crystal Skull...used by a Russian Soldier, oddly enough.
 * A thug uses one in Black Lagoon to breach a door.
 * George in The Book of Eli has one.
 * The Wild Bunch seems to love them, as almost the whole gang uses them at one point or another.
 * For that matter, so do The Untouchables on the opposite side of the law.
 * Red Dead Redemption gives it the generic title of pump-action shotgun. Another rare appearance by the civilian version given that the Trenchgun was not even developed yet.
 * Gunslinger Girl has this as Triela's shotgun of choice, complete with the bayonet.
