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. The federal ban which was in effect from 1994 to 2004 defined a magazine capable of holding more than 10 rounds of ammunition as a large capacity ammunition feeding device. Likewise, the state of California defines a large capacity magazine as "any ammunition feeding device with a capacity to accept more than 10 rounds." Such devices are commonly called high-capacity magazines. Among states with bans, the maximum capacity is 10 to 20 rounds. Several municipalities, such as New York City, restrict magazine capacity to 5 rounds for rifles and shotguns. Magazine bans by country Canada With the passage of Bill C-17 in 1993 under Prime Minister Kim Campbell (in response to the 1989 Ecole Polytechnique Massacre), magazines designed for use in semi-automatic centrefire rifles and semi-automatic shotguns became limited to five rounds, and magazines designed for use in handguns are limited to 10 rounds. Magazines designed for use in semi-automatic rimfire rifles, as well as manually operated long guns, are exempt from the magazine capacity restrictions. In recent years, there has been a growing trend of ways to legally work around the magazine capacity restrictions. Numerous semi-automatic centrefire rifles also happen to accept handgun magazines, thereby legally increasing magazine capacity. Numerous rifle and handgun magazines designed for a particular caliber also happen to fit an over-the-limit number of smaller caliber rounds, also legally increasing magazine capacity. Russia In Russia, all magazines for use with any type of firearm are limited to no more than 10 rounds. United Kingdom There are no capacity restrictions on detachable magazines in the United Kingdom. Rifles & Pistols High-capacity magazines may be used in any legal rifle or long-barrelled pistol.
