M3 submachine gun

submachine gun

Stamped from sheet steel to cost about $15 apiece against the Thompson's much higher price, the M3 traded polish for volume and became known as the 'Grease Gun' for its resemblance to a mechanic's tool. Roughly 600,000 were built before the war ended, and it stayed in US service for decades afterward.
