This week, rather than talk about “This Goofy Gun” we’re going to change things up a little and take a look at “This Greasy Gun.”

Most folks think that the M3 “Grease Gun” submachine gun of World War II fame was created in response to the success of the German MP38, MP40 and British Sten machine guns. While partly true, that’s not the whole story. Here’s the rest of the storied, and musical, history of the M3 Grease Gun.

Many people know that the M3 was produced by General Motors’ Guide Lamp Division. What they don’t know is that the design was envisioned much, much earlier, or so I hear. By 1940, GM was getting a little worried about competitive pressure from AMC’s Gremlin impacting sales of their Cadillac LaSalle. That Gremlin was a beast of a car wasn’t it? Anyway, to add some kick to the planned 1941 model, GM hired long lost brother of the infamous Edward Hyde of Dr. Jekyll fame, George Hyde, to design some killa’ glovebox accessories for ’41 model sales incentives. Having the same family wild hair as crazy man Mr. Hyde, George took to designing prototypes of the M3. “Heck, I just wanted to amp up the “Boom!” factor for our customers. Most companies were putting a flashlight mount in the glovebox, but I figured a .45 ACP submachine gun would be way more spiffy,” commented GM Engineer George Hyde.

Alas, GM discontinued the Cadillac LaSalle in 1941 and the M3 Glovebox Submachine Gun was never marketed. But the story did not end there. In 1941, the Ordnance Department asked the Army to submit requirements for a new submachine gun. In addition to specification of .45 ACP caliber, inexpensive stamped-metal construction and  automatic fire control, the new gun must have a really catchy theme song.

Seeing opportunity to resurrect Hyde’s previous project, and do a little contract work with a very young John Travolta, GM’s Guide Lamp Division started stamping out prototypes of the M2 and finally M3. As for the theme song? That was Travolta’s job. And now you know the real story behind that catchy jingle from the movie Grease – You’re the One That I Want. Not having been born yet, Olivia Newton John was not available for promotional campaigns. Besides, those skin-tight pants were way too risque for pre-war America.
