The Pump Action Shotgun is one of the many shotguns available throughout the Grand Theft Auto series of games. In Grand Theft Auto III, the shotgun's model is a Remington 870P. For Vice City and San Andreas, it resembles an Ithaca 37. For Liberty City Stories and Vice City Stories, it is an Over and Under shotgun, although it functions like a pump shotgun. A unique quality attributed to the shotgun is that is fires several projectiles at once, and at close range, it can disable even the most armored targets, and another advantage is that it can be purchased at most Ammu-Nation stores for a cheap price. A large disadvantage with this shotgun is that the player cannot run with it (minus in GTA Liberty City Stories and Vice City Stories), and due to the pump mechanism has a very slow rate of fire, thus cannot be used effectively against multiple enemies, plus it's nearly impossible to fire at long ranges.
In Grand Theft Auto IV, it is referenced in-game as the Pump Shotgun and it is modeled after the Ithaca 37 "Stakeout" shotguns, with a short barrel and magazine tube, and a pistol grip. The shotgun holds eight shells, however the length of the barrel and magazine tube should only allow it to hold four.
