High-capacity magazine (or large-capacity magazine) is a legal term that, in the United States, generally refers to magazines capable of holding more than 10 rounds, although the number of rounds varies among different jurisdictions and for different kinds of firearms.
In the U.S. since the 1980s, magazine capacity has been a subject of debate regarding civilian firearms. Many assault weapon bans since then have included or been accompanied by high-capacity or large-capacity magazine bans. The National Rifle Association (NRA) defines high-capacity magazine as "[an] inexact, non-technical term indicating a magazine holding more rounds than might be considered 'average.'" In 2011, the Glock website said that a standard magazine for its 9mm semiautomatic pistol is between 13 and 17 rounds. Gun rights groups such as the Jews for the Preservation of Firearms Ownership (JPFO) have endorsed the use of high-capacity magazines. Some commentators and gun rights advocates call such devices "so-called high-capacity magazines," to highlight the arbitrary nature of the designation. The debate regarding magazine capacity intensified in the U.S. after the December 2012 Sandy Hook Elementary School shooting. In January 2013, President Barack Obama included a ban on gun magazines with capacities of more than 10 rounds in a list of gun-control laws he asked Congress to pass.
