WWII M3 Grease Gun Faux MK3 Suppressed Barrel. An original barrel made to look like an original Suppressed Barrel. Total length is 16 1/2 inches and chambered for .45 Cal. Excellent. The M3 is an American .45-caliber submachine gun adopted by the U.S. Army on 12 December 1942, as the United States Submachine Gun, Cal. .45, M3. The M3 was chambered for the same .45 ACP round fired by the Thompson submachine gun, but was cheaper to mass produce and lighter, at the expense of accuracy. The M3 was commonly referred to as the "Grease Gun" or simply "the Greaser", owing to its visual similarity to a grease gun, a mechanic's tool. The M3 was intended as a replacement for the Thompson submachine gun, and began to enter frontline service by mid-1944. By late 1944, the M3A1 variant was introduced, which also saw use in the Korean War and later conflicts. The M14 rifle, adopted in 1959, was intended to replace the M3A1 (as well as the M1 Garand, M1918 Browning Automatic Rifle and the M1 carbine) but the recoil of the M14's 7.62×51mm NATO cartridge proved too powerful for the submachine gun role. The M14 was in turn replaced by the M16 rifle in 1964, and this weapon and its subsequent shorter iterations (XM-177, firing the intermediate 5.56×45mm NATO cartridge) was a better replacement for the M3A1. M3A1 submachine guns were retired from U.S. frontline service after 1959, but continued to be issued, for example as backup weapons for armored vehicle crews as late as the Gulf War (1990–1991). Many overseas US military bases continued to issue these for certain crews into the mid to late 1990s.
