Watch As Brandon Herrera Shows Us The M3A1 Grease Gun – America’s $15 SMG

When I was stationed at Fort Hood, with the 1st/12th Cav, 1st Cav Division, one of my assigned weapons was the M3A1 ‘Grease Gun’. Prior to that, I had never even seen one, except in some war movie.

So when I found out I could have one assigned to me, I jumped at the opportunity. Yeah, I know it was a little “old school” even back in the 70’s, but I didn’t care.

It wasn’t particularly pretty, and the rate of fire (450 rounds per minute), wasn’t as fast as the Thompson’s 600 to 900 rpm, but there was something about carrying a submachine gun chambered in 45acp. I knew, that when I aimed and fired (especially at close range), whatever I hit, was sure as hell going DOWN!!

So instead of me going on and on about the past, I will place some crucial technical information about the weapon below and I’ll let Brandon Herrera do all the talking (and shooting).

About the M3A1 courtesy of Wikipedia:

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.

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.

The M3 was commonly referred to as the “Grease Gun” or simply “the Greaser,” owing to its visual similarity to the mechanic’s tool.

The M3 was intended as a replacement for the Thompson, and began to enter frontline service in mid-1944. The M3A1 variant was used in the Korean War and later conflicts.
