Semi-automatic firearm
Semi-automatic firearms automatically load a round into the chamber after the weapon is fired, but still require a trigger pull for each round that is fired. For example, if someone were to shoot ten rounds in a semi-automatic firearm, they would need to pull the trigger ten times (once for each round fired). Compare this to a fully automatic firearm, which will continue to fire as long as the trigger is held or until it runs out of ammunition. Pistols, rifles, and shotguns can all be semi-automatic.See also: Semi-automatic handgun, Semi-automatic rifle
