Pump action shotguns are a subclass of
shotguns that are distinguished in the way in which spent shells are extracted and fresh ones are chambered. The weapon has two barrels stacked vertically, with the bottom tube storing between 3 and 7 shells depending on the model. New shells are loaded by pulling a pump handle attached to the bottom tube toward the user, and then pushing it back into place. This same action simultaneously flings the most recently fired shell out the side ejection port. The length of these shotguns are aproximately 24in to 34in's.
