A semiautomatic firearm is a type of gun that automatically reloads after each shot but requires the shooter to pull the trigger for each round fired. This means that once the trigger is pulled, a bullet is fired, and the next round is chambered without any additional action from the shooter. Semiautomatic weapons are commonly used in various contexts, including hunting, sport shooting, and self-defense. They differ from fully automatic firearms, which continue to fire as long as the trigger is held down, and from manual firearms, which require the shooter to manually load each round.
