How many bullets does a 45 acp hold?

Answer 1

Most common 45s (1911 models) hold 7 rounds in the magazine (single stack), one in the chamber. There are magazines for the 1911 (45 acp) that hold 10, 12, 15 or more. These are quite long and protrude out of the frame several inches.

Some of the more modern 45s hold the rounds in a staggered fashion. These can hold 10 or more rounds. The trade off is that these higher-capacity 45s have a larger diameter grip (where the magazine goes). This can make shooting difficult for those with smaller hands.
