Designed by Gordon B. Ingram, the MAC (Military Armament Corporation) series machine pistols were first designed in 1964. It is a simple machine pistol with few moving parts (making for easy maintenance) and a low cost of manufacture. The model 10 (AKA MAC-10) uses .45 ACP rounds, while the model 11A1 uses .380 ACP rounds and the model 11/9 is uses 9mm rounds. The MAC-11 series boasts a greater rate of fire due to the less powerful rounds, and can empty its impressive magazine in 1.57 seconds. It is essentially a spray and pray weapon on auto fire, since the rate of fire makes controlling the recoil (especially in the .45 cal series) extremely difficult. Its compact size, light weight, high caliber, large magazine, and blistering rate of fire make it an extremely lethal weapon with great stopping power in tight quarters
