The MAC-11 is a smaller, lighter version of the MAC-10, chambered in .380 ACP. Designed by Gordon Ingram as a more compact alternative for situations where the MAC-10's size was a limitation. Even higher cyclic rate than the MAC-10 at approximately 1,200 rounds per minute. Like the MAC-10, original MAC production ended in the mid-1970s. The MAC-11 design continued through SWD Inc. as the M11/Nine (9mm) and Cobray M11. Semi-auto civilian pistol versions were widely produced.
