Vulcan M-11-9

The Vulcan M-11-9 is a semi-automatic, closed bolt pistol manufactured by Vulcan Armament.

The M-11-9 is a knockoff of the Ingram MAC-10 series which is an open bolt, fully automatic machine pistol. While the Ingram uses proprietary magazines, the Vulcan used readily available surplus 32 round sten magazines. Utilizing the 9x19mm NATO cartridge, it is a civilian legal version of the military weapon.

There are several carbine versions of the M-11-9.
