A high-capacity magazine ban is a law which bans or otherwise restricts high-capacity magazines, detachable firearm magazines that can hold more than a certain number of rounds of ammunition. For example, in the United States, the now-expired Federal Assault Weapons Ban of 1994 included limits regarding magazines that could hold more than ten rounds. As of 2022, twelve U.S. states, and a number of local governments, ban or regulate magazines that they have legally defined as high-capacity. The majority of states do not ban or regulate any magazines on the basis of capacity. States that do have large capacity magazine bans or restrictions typically do not apply to firearms with fixed magazines whose capacity would otherwise exceed the large capacity threshold.
