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. [13] 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. [ 13 ]
The M3 has a dummy tube just for stock attachment. Benelli's M3T is an OEM variant, where the butt-stock and dummy tube have been replaced with a pistol grip and up-folding skeleton butt-stock. Benelli's SuperNova pump-shotgun and MR1 self-loading rifle have similar butt-stock attachment to the M3, so this adds two new butt-stock options to M3.
Unlike the many early 3D-printed firearm designs, which were overbuilt in order to withstand the pressures and strain on the material from modern gunpowder cartridges, the Reprringer is small and only slightly larger than an equivalent gun made from steel.

This is a historic (index) list of United States Army weapons and materiel, by their Standard Nomenclature List (SNL) group and individual designations — an alpha-numeric nomenclature system used in the United States Army Ordnance Corps Supply Catalogues used from about 1930 to about 1958.
All metal-linked ammunition was reserved for the Army Air Force and Naval Aviation. When the US Army Air Force .30-caliber machine gun was superseded by the .50-caliber machine gun mid-war, all .30-caliber ammunition began to be belted in M1 250-round belts for infantry use or M3 100-round woven belts for use in vehicles and tanks.
The primary differences between the two weapons include: development time and intent (the K1 took less time to develop and entered service sooner than the K2, and was developed originally as a submachine gun because it was intended to replace the M3 Grease Gun; the K2 was developed from the start as a service rifle); rifling (K1: 1-in-12 twist ...
