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.
The pistol has had a somewhat rocky start with severe quality control issues on early production guns. Early M-11-9's had feeding issues that were eventually traced to poor quality metal used in the feed ramp. There were also issues of failure-to-fire and unintentional full-auto fire (UFAF) that were traced to poor quality firing pins and sear assemblies. The quality issues have since been rectified. Newer sear assemblies are almost impossible to get going full auto, even when "bump firing".
There are several carbine versions of the M-11-9.
