The M3 Grease Gun was the cheap American gun built to replace the Thompson during World War II. Designed for fast, inexpensive mass production, it looked so crude that American soldiers quickly gave it a nickname that stuck: the “Grease Gun.”
This video explores how George Hyde and production engineer Frederick W. Sampson helped turn the M3 into a weapon built around stamped steel, welding, and factory efficiency rather than expensive machining.
With only 73 parts and very little expensive machining, the M3 was radically cheaper and simpler to manufacture than the Thompson. =
But cheap production came with consequences: early guns suffered manufacturing problems, soldiers questioned the weapon’s reliability, and many initially preferred the famous Thompson.
Over time, however, the compact M3 submachine gun proved especially useful for tank crews, patrols, and soldiers fighting at close range.
It was never as glamorous as the Thompson—but its simplicity helped it remain in American service long after World War II.
