The Military Armament Corporation Model 10, officially abbreviated as "M10" and "M-10", and more commonly known as the MAC-10, is a compact, blowback operated machine pistol that was developed by Gordon B. Ingram in 1964. The Morrow Project model is chambered in 9x19mm Parabellum. A two-stage suppressor by Sionics was designed for the MAC-10, which not only abated the noise created, but made it easier to control on full automatic.
The Morrow Project M10 issue includes the Sionics suppressor and a folding stock, and is commonly issued to vehicle teams.
