A firearm that can hold multiple cartridges and fire them each time the trigger is pulled is an?

• A. Single-shot
• B. Semi-Automatic
• C. Revolver
• D. Break-action

Answer: (B)

It’s about how the firearm handles loading and firing between shots. A semi-automatic firearm holds multiple cartridges in a magazine and uses the energy from each firing to eject the spent casing and chamber the next round. That means you can keep firing with one trigger pull per shot, automatically cycling the next cartridge until the magazine is empty.

Single-shot designs hold only one cartridge and must be reloaded after each shot. Break-action firearms are typically single-shot, opened to load one cartridge at a time. A revolver stores several rounds in a rotating cylinder and can fire multiple times, but it doesn’t feed from a fixed magazine and its mechanism isn’t self-loading from a magazine with each trigger pull in the same way as a semi-automatic.

So the description—holding multiple cartridges and automatically cycling to the next round with each trigger pull—best matches a semi-automatic firearm.
