'''Pump action''' is a type of manual [[firearm action]] that is operated by moving a sliding [[handguard]] on the gun's [[forestock]]. When [[shooting]], the sliding forend is pulled rearward to eject any expended [[cartridge (firearms)|cartridge]] and typically to cock the [[hammer (firearms)|hammer]] or [[firing pin|striker]], and then pushed forward to load a new cartridge into the [[chamber (firearms)|chamber]].  Most pump-action firearms use an integral [[tubular magazine]], although some do use detachable [[box magazine]]s. Pump-action firearms are typically associated with [[shotgun]]s, although it has also been used in [[rifle]]s, [[grenade launcher]]s, and other types of firearms. A firearm using this operating mechanism is colloquially referred to as a '''pumpgun'''.

Because the forend is manipulated usually with the support hand, a pump-action firearm is much faster than a [[bolt-action rifle|bolt-action]] and somewhat faster than a [[lever-action]], as it does not require the [[trigger (firearms)|trigger]] hand to be removed from the trigger while reloading. Also because the action is cycled in a linear fashion, it creates less [[torque]] that can tilt and throw the gun off aim when repeat-firing rapidly.
