Facts: The MAC-10 submachine gun was originally designed by Gordon B. Ingram in the 1960s, designed to be a compact, high rate of fire sub machinegun ideal for concealed carry. The M10 also had a folding retractable stock and was fed by a modified M3 Grease Gun magazine. Though compact, the weapon was not very light weight, weighing at 6lbs unloaded without a suppressor and over 8lbs loaded with the suppressor. Although it was heavy, the weapon was still not very controllable with a rate-of-fire of 1090 rounds per minute in .45 ACP. The two-stage removable suppressor design came from a man named Mitchell BerWell III who teamed up with Ingram to design a suppressor for the M10. The caliber they used, .45 ACP, was naturally subsonic making the platform extremely quiet though not as compact and concealable, but did assist in that the suppressor gave the user something to hold to help control it. The barrel of the M10 was also threaded to allow for the quick attaching and detaching of the suppressor. These weapons were used by US Special Operations during covert operations in Vietnam for its compact size and how quiet it was. Due to the combination of the weapons poor controllability and accuracy, the MAC weapon series was “fit only for combat in a phone booth” as described by the International Association of Police Chiefs weapons researcher David Steele.
