semi-auto

One trigger, one

Semi-auto is short for semi-automatic, describing a firearm that fires one round per trigger pull and automatically loads the next round from the magazine.

This distinguishes it from fully automatic weapons, which continue firing while the trigger is held, and from manual-action firearms like bolt-action rifles.

He bought a semi-auto for home defense.

The term appears in gun enthusiast discussions, news coverage of shootings, and debates about firearm regulations.
