The Military Armament Corporation Model 10, officially abbreviated as "M10" or "M-10",^[5] and more commonly known as the MAC-10, is a compact, blowback operated machine pistol/submachine gun that was developed by Gordon Ingram in 1964. It is chambered in either .45 ACP or 9mm. A two-stage suppressor by Sionics was designed for the MAC-10, which not only abates the noise created but makes it easier to control on full automatic (although it also makes the gun far less compact and less concealable).^[6]

Military Armament Corporation never used the "MAC-10" nomenclature in its catalogues or sales literature, but "MAC-10" is frequently used by Title II dealers, gun writers, and collectors.^{[citation needed]} For a decade, the semi-automatic pistol version of the weapon was forbidden in the U.S. under the assault weapons ban enacted by Congress in 1994.
