M3 Grease Gun
Caliber: .45ACP (also 9x19mm Luger/Para in M3A1) The M3 submachine gun, also known as Grease Gun, was developed as a cheaper war-time alternative to the famous Thompson M1 and M1928 submachine guns. The M3 and M3A1 were developed and manufactured by General Motors Corp. The M3 was introduced in 1942, and a simplified M3A1 was introduced in 1944, and remained in service (in the USA) until 1960 or so, and also was exported. The M3 is a full-auto only, blowback operated firearm. The receiver is made from steel stampings. The M3 featured a spring-loaded ejection port cover (also acting as a safety) and a crank-type bolt retracting (cocking) handle at the right side of the receiver. In the M3A1 the designers removed the cocking handle assembly (it was prone to malfunctions) and replaced it with a simple finger hole in the bolt body, accessible through an enlarged ejection window. Also, M3A1's were able to be converted to use 9mm Luger rounds by replacing the barrel, bolt, and installing the magazine adaptor to use British Sten magazines. Both the M3 and M3A1 fire from the open bolt. The retractable stock, made from steel wire, can be used as a cleaning rod (when detached). It also features a magazine loading tool. Some M3s and M3A1a were also fitted with flash hiders. The sights are fixed and are located at the top of the receiver. Experience one TODAY at Midwest Gun and Range!
