Brief Info on the M3A1 Grease Gun

The M3 was a blow back submachine originally fielded in December 1942. It could only be fired on fully-automatic.

The M3 submachine gun, also known as Grease gun, was developed as a cheaper war-time alternative to famous Thompson M1 and M1928 submachine guns.

M3 and M3A1 were developed and manufactured by General Motors Corp. M3 was introduced in 1942, and simplified M3A1 was introduced in 1944

In M3A1 the designers removed cocking handle assembly (it was prone to malfunctions) and replaced it with simple finger hole in the bolt body, accessible through 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 M3 and M3A1 fired from the open bolt.
The retractable stock, made from steel wire, could be used as cleaning rod (when detached), it also featured a magazine loading tool. Some M3s and M3A1a were also fitted with flash hiders. The sights were fixed and were located at the top of the receiver.

The weapon's compact size makes it ideal for use inside tanks, and it remains an issue weapon even today

The M3A1 was used during World War II ,Korea and Vietnam.

Following World War II, the role of submachine guns was greatly diminished with the introduction of assault rifles and light portable machine guns.

Submachine guns are still used by Special Forces, air crews, armoured vehicles, counter-terrorist units, and naval personnel.
