M3 Submachine gun (SMG), or named Grease Gun, was an US made open bolt type SMG adopted by US Army in 1942 during the WWII. In 1941, the US Army observed the effectiveness of the SMGs in Western Europe, like the German 9mm MP40 and British Sten Gun, hence initiated a study to develop its own Sten-type SMG in 1942. In 1944, M3A1 was developed as an improved version of the Grease Gun.
Most of the M3 or M3A1 was produced for champered .45 ACP ammo, and 1000 pcs of the M3 equipped with an integral sound suppressor (designed by Bell Laboratories). Also, around 25000 pcs of M3 was champered 9mm luger ammo which has a different barrel, bolt carrier and magazine well from the .45 M3s. It can directly use with Sten magazine or the a replacement 9mm STEN magazine. The 9mm version M3 also comes in conversion kits, but only 500 kits be obtained.
