What is a key characteristic of semi-automatic pistols?

A key characteristic of semi-automatic pistols is that they fire one bullet with each trigger pull. This means that when the shooter pulls the trigger, the pistol will discharge a single round and then automatically cycle the action to load the next round from the magazine into the chamber. This allows for a quicker follow-up shot compared to other types of firearms that may require manual action to load the next round after firing.

This characteristic is what distinguishes semi-automatic pistols from revolvers, which require the cylinder to rotate to bring a new round into alignment with the barrel after each shot, and from fully automatic firearms, which continue to fire as long as the trigger is held down. Understanding this function is essential for those using semi-automatic pistols, as it impacts shooting technique and safety practices.
