The M3, nicknamed the 'Grease Gun,' was a cost-effective and compact .45 ACP submachine gun used by U.S. forces during WWII and beyond.
Curious about how much your M3 'Grease Gun' sub machine gun is worth? Whether you’re looking to sell or simply understand current pricing, we’ll help you assess the market value of your firearm.
Developed to replace the Thompson, the M3 was stamped and welded to cut production costs while maintaining firepower. Its nickname came from its resemblance to a mechanic’s grease gun. Though having a slower rate of fire and being less refined than its predecessor, the M3 proved rugged and reliable, serving into the 1990s in some military units. Its more complicated features such as the crank-style charging handle would be illuminated on the later M3A1 variant.
