context_page_description: In firearms terminology, an action is the functional mechanism of a breech-loading weapon that handles the ammunition, or the method by which that mechanism works. Actions are technically not present on muzzleloaders, as all those are single-shot weapons with a closed off breech and the ammunition is manually loaded through the muzzle. Instead, the muzzleloader ignition mechanism is referred to as the lock.
  Actions can be categorized in several ways, including single action versus double action, break action versus bolt action, and others. The term action can also include short, long, and magnum if it is in reference to the length of the rifle's receiver and the length of the bolt. The short action rifle usually can accommodate a cartridge length of 2.8 in or smaller. The long action rifle can accommodate a cartridge of 3.34 in, and the magnum action rifle can accommodate cartridges of 3.6 in, or longer in length.
context_section_description: In pump action or slide action firearms, a sliding grip at the fore-end beneath the barrel is manually operated by the user to eject and chamber a new round.  Pump actions are predominantly found in shotguns.  An example of firearms using the pump action are the Remington 870 and Winchester Model 1897.
