Introduction

The MAC-10 is an early Cold War era sub machine gun of US origin. It was developed in the 1960's by Gordon Ingram. The name MAC-10 is a popular name, the actual factory designation is Model 10 or M10. The M10 has become an iconic weapon used by gangsters in Hollywood movies.

Design

The M10 looks similar to the Israeli Uzi and employs a similar telescoping bolt that wraps around the barrel. All models are blowback operated and fire from an open bolt position. Due to the light bolt the rate of fire is very high. Many models were delivered with the iconic two stage suppressor which reduces the noise and muzzle flash considerably. Additionally a leather strap can be attached at the front to serve as a forward grip.

Firepower

The M10 fires the .45 ACP or 9x19mm round from a 30 or 32 round magazine respectively. The smaller M11 fires the .380 ACP round from a 16 or 32 round magazine. The rate of fire is very high, about 1.100 rpm for the M10 and 1.200 for the M11. The effective range is quoted as 50 meters for the .45 ACP model and 80 meters for the 9x19mm model.

Users

The M10 was never adopted as a standard issue military weapon, but was used by various military, special forces and law enforcement organizations in the USA, South America and other parts of the world.
