MAC10

The MAC-10, officially the M10, is a compact machine pistol developed by Gordon B. Ingram in 1964. It is chambered in either .45 ACP or 9x19mm Parabellum. The design is known for its extreme rate of fire and simplicity, featuring a telescoping bolt and a prominent suppressor that was often integrated into its design, though not always included. Its small size and high rate of fire made it popular in certain circles, though its controllability at that rate of fire was a significant challenge.

Production began in the late 1960s and continued through the 1970s, with various manufacturers producing the weapon. The MAC-10's distinctive look and its association with media portrayals have cemented its place in popular culture. While never widely adopted by major military forces, it saw limited use by special operations units and law enforcement agencies. Its relatively low cost and ease of manufacture contributed to its prevalence in the civilian market and illicit arms trade. The MAC-10 is recognized for its straightforward blowback operation and its stamped sheet metal construction.
