Pump or Slide Action
Used in both shotguns and rifles, pump action allows a hunter to quickly eject and chamber new ammunition. It is typically loaded from the bottom into a tubular magazine. The action is opened when the forearm is pulled back to the rear of the firearm. Pushing the forearm forward moves the ammunition from the magazine into the chamber and closes the action so that the firearm is loaded and ready to be fired. On most pump-actions, a slide lever located by the trigger guard releases the action so you can inspect the chamber or unload the firearm.
