[6] This weapon is sometimes confused with the Sylvia & Wayne Daniels M-11/9, its successor the Leinad PM-11, or the Vulcan M-11-9, both of which are later variants of the MAC chambered for the 9 mm Parabellum cartridge.

The charging handle rotates to 90 degrees to lock the bolt in the forward position thus preventing the weapon from being cocked.

The second safety is a slider that is pushed forward to lock the trigger, which in turn pins the bolt to the rear (cocked) position.

Listed as 1,200 rounds per minute,[2] the MAC-11's high cyclic rate is able to empty the entire 32-round magazine in about two seconds, which many users view as a drawback.

Without proper training, the natural tendency of the inexperienced shooter is to hold down the trigger, discharging the entire magazine, often with poor accuracy due to recoil.
