mac10

The Military Armament Corporation Model 10, officially abbreviated as "M10" or "M-10", and more commonly known as the MAC-10, is a compact, blowback operated machine pistol/submachine gun that was developed by Gordon B. 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 concealable). 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.
The term "MAC-10" is commonly used in unofficial parlance. Military Armament Corporation never used the nomenclature MAC-10 on any of its catalogs or sales literature, but because "MAC-10" became so frequently used by Title II dealers, gun writers, and collectors, it is used more frequently than "M10" to identify the gun.
