High-capacity magazine

A high-capacity magazine (or large-capacity magazine) is a magazine capable of holding a higher than normal number of ammunition rounds for a particular firearm (i.e. more than in a standard magazine for that firearm).

A magazine may also be defined as high-capacity in a legal sense, based on the number of rounds that are allowed by law in a particular jurisdiction.^[1] For example, in the United States, the now-expired Federal Assault Weapons Ban of 1994 restricted magazines that could hold more than ten cartridges.
