Pump Shotgun

"Standard shotgun ideal for short-range combat. A high-projectile spread makes up for its lower accuracy at long range."

- GTA V description on the Rockstar Games Social Club.

The Shrewsbury Pump Shotgun is a shotgun first featured in Grand Theft Auto 2 and appearing in all Grand Theft Auto games since then.

Grand Theft Auto 2
The shotgun Grand Theft Auto 2 is used by Special Agents and gang members if their hatred towards the player is high enough. In GTA 2, the shotgun bears some resemblance to a Mossberg 500 with a pistol grip and no stock.

3D Universe
A unique quality attributed to the shotgun is that it fires several projectiles at once, and at close range two accurate spreads will destroy most non-bulletproof vehicles. The shotgun pellets can also knock down enemies. Another advantage is that it can be purchased at most Ammu-Nation stores for a cheap price or found in Police Vehicles, making it both powerful and inexpensive.

A large disadvantage with this shotgun is that the player cannot run with it in GTA III, GTA: Vice City and GTA: San Andreas. Also, the pump mechanism has a very slow rate of fire, so it cannot be used effectively against multiple enemies.

In Grand Theft Auto III, the shotgun's in-game model is a Remington 870 with a Police Folding Stock. While obscured in game in GTA: Advance, the shotgun icon for GTA III was reused for Advance, implying the shotgun in GTA Advance is similar to that of GTA III. For Vice City (where it is known as the "Chrome Shotgun") and San Andreas, it resembles an Ithaca 37 with a wooden buttstock. For Liberty City Stories and Vice City Stories, it is an "Over and Under" shotgun. However, it functions like a pump shotgun.

HD Universe
In Grand Theft Auto IV, the Pump Action Shotgun is an Ithaca Model 37 Stakeout, though is based on the Auto Hardball Model 870 Airsoft variant. Its design is similar to the Stubby Shotgun. The shotgun holds eight shells, although with the length of the barrel and magazine tube it should only hold four.

The Pump Shotgun can be purchased from the back-alley gun shops for $1200, and each additional magazine is worth $100. The Pump Shotgun is not available from Little Jacob. The LCPD, NOOSE, and FIB, in addition, use this gun as a secondary weapon. It can be picked up from them when they are killed. This gun, rarely used on Multiplayer but extensively used on Single-Player, is extremely powerful. It will kill any Single-Player foes with one shot (even fully healthy fully armored ones at point blank), and the most needed for Multiplayer will be about 3 or 4 leg shots. This is a one-hit kill at close range on any part of the body. It cannot be fired from cars. Members of the Russian Mafia and biker gangs will sometimes have it as a secondary weapon.

The Pump Action Shotgun in Grand Theft Auto V is modeled after the Mossberg 590 Cruiser, with several modified parts such as the pistol grip housing that accepts AR-15 pistol grip, and the stock that accepts M4-styled stocks, which in this case, is the Magpul MOE stock.

Locations
In the 3D Universe and HD Universe, Police Cars will have a shotgun with five rounds in them, which is added to the player's arsenal once they enter the vehicle. In GTA IV Police Cars will instead contain a Combat Shotgun.

Glitch
There is a glitch in GTA V if you blind fire the sawed off shotgun it will be pumped after the shot then be pumped again when the gun goes back in cover which in reality would waste a shell.

There is a glitch in GTA IV that if you keep crouching and shooting at the same time, the weapon will become automatic but more powerful than the Combat Shotgun. There is also another glitch with this shotgun, in which the player can make it fire very rapidly, all eight shells can be fired in around the same time it takes to fire two normally.

Trivia

 * In the 3D Universe, it is possible to shoot the Pump Action Shotgun without pumping it. After shooting the Pump Action Shotgun, jump quickly and the animation of the player character pumping the Pump Action Shotgun will be skipped. In GTA: San Andreas, the player must crouch, shoot while crouching and then stand up, causing the pumping animation to be skipped, though the sound of the pump is still heard.
 * In the 3D Universe, the Pump Action Shotgun does not need to be reloaded; it just needs to be pumped.
 * In the 3D Universe, a shotgun typically fires three pellets that travel in three visible lines. In the HD universe, the shotgun more realistically scatters pellets in random trajectories, rather than rigid lines.

GTA III

 * The Pump Action Shotgun in GTA III is equivalent to the Stubby Shotgun in later GTA games, in that the shotgun shoots five pellets per shell, kills in one shot at close range and can destroy a car in two shots, which makes the GTA III shotgun and the Stubby Shotgun roughly the same in terms of stats.
 * In GTA III, when passing trough the mafia territory after the mission Sayonara Salvatore, the mobsters wield shotguns as well, but when they shoot at a car, which in the player will be (otherwise, they wouldn't shoot at a vehicle if the player isn't in it), the car would explode from one shot. This making impossible to drive a vehicle in Mafia territories.
 * In the IOS version, the player can sometimes fire multiple shots without pumping the shotgun by hitting the fire button immediately after firing. If a pedestrian is in range, auto-aim will lock onto it and the gun will fire, skipping the pumping animation. Alternatively, If a pedestrian bumps into Claude as he is pumping the shotgun, the animation will be skipped, allowing you to fire again immediately.

GTA Vice City

 * In early screenshots and trailers for GTA: Vice City, the Pump Action Shotgun had the same model as the Pump Action Shotgun from GTA III, but it was later changed. It is still hidden in the files.

GTA San Andreas

 * The Pump Action Shotgun in GTA: San Andreas ejects a shell before Carl pumps the shotgun. This is incorrect, as the shell should be ejected along with the pump.
 * Before reaching "Gangster" skill level with the Pump Action Shotgun, Carl fires the shotgun without utilizing the stock.
 * In GTA San Andreas, if the cheat code ammo never runs out "FULLCLIP" is activated, then the pumping sound will not be heard.

GTA IV

 * The GTA IV rendition of the shotgun bears a "MODEL No. 69" etching (alongside another reading "~ 12.GAUGE ~") which is under the other reading.
 * The Ithaca 37 "Stakeout" shotgun is considered to be a Stubby Shotgun in the 3D Universe. However, it is called the "Pump Action Shotgun" in GTA IV, and acts like one.

GTA V/Online

 * The Pump Shotgun is favored during GTA Online Heists, as it is used during The Fleeca Job and The Humane Labs Raid.
