Pistol action types include which of the following?

• A. Single shot
• B. Both single shot and semiautomatic
• C. Semiautomatic
• D. Revolver action

Answer: (B)

Pistol action types are about how the firearm loads and fires another round after each shot. Single-shot pistols are loaded with one round and must be reloaded after every shot. Semiautomatic pistols use the energy from the fired cartridge to eject the spent case and chamber the next round from a magazine, continuing this cycle with each trigger pull.

Revolvers use a rotating cylinder to present a new round, which is a different mechanism from the semiautomatic cycling and is usually treated as its own class rather than just another action type in this context. Because pistols can be single-shot or semiautomatic, the most complete option reflects both of these common action types. The other choices are incomplete because they omit one of these modes, or they try to classify revolvers as merely another action type rather than as a separate category.
