What is a key characteristic of semi-automatic pistols?

The key characteristic of semi-automatic pistols is that they automatically load the next round after each shot. This means that when the shooter pulls the trigger, a round is fired, and the mechanical action of the firearm ejects the spent cartridge casing, then chambers a new round from the magazine all in one continuous action. This allows for quicker follow-up shots compared to manual-loading firearms, where the shooter must intervene after each shot to load another round.

Semi-automatic pistols are designed for efficiency and ease of use, accommodating multiple rounds without the need for the shooter to perform any manual actions beyond pulling the trigger. This self-loading functionality is what distinguishes them from revolvers or single-shot firearms, providing greater firepower and reduced time between shots in self-defense or competitive contexts.
