M3 Grease Gun


The M3 "Grease Gun" (more formally United States Submachine Gun, Cal. .45, M3/M3A1) was a submachine gun developed by the United States during World War II as a cheaper substitute for the Thompson. It was nicknamed the Grease Gun because of its resemblance to an automotive grease gun. The M3 used the blowback method of operation. It could be fired only in fully-automatic mode, but experienced soldiers could usually fire single shots with it due to its very low rate of fire (400 to 450 rounds per minute). Used in some parts of the US Army up to the early 1990’s.
