Semi-Automatic Defined

In a semi-automatic firearm, whether it’s a pistol, rifle, or shotgun, when the round is fired, the expanding gas from the cartridge launches the projectile and then opens the chamber, ejecting the spent cartridge and, if available, using a spring system to slide the next cartridge into place ready for the next trigger pull.

The gun will not fire the next round and most guns are designed to prevent this from happening. This means one trigger pull for each shot.
