POTD — US Navy Tommy Gun

Who doesn’t like a Thompson 45 with carrying case, drum magazine, stick mags, and a forward pistol grip? This one belonged to the US Navy it seems by the markings.

I sure do.

Carrying case. Drum Mag. Stick Mags. Cleaning rod.

    This post intrigued me, especially since the model number had obviously been overstamped to read ‘Model of 1928,’ so I did a little research on it. Unlike Garands, I wasn’t able to find a definitive serial number guide to determine when this gun was manufactured, but I did find some interesting information about the Navy model. Apologies for pasting in the text, but you had to read through it a bit to get to the good part. I’ve also included the link as a citation.

    “The 1928 Navy Model

    The most prolific Colt-manufactured Thompson model was the 1928 Navy model also referred to by collectors as the Colt overstamp, the 1921 overstamp, 28 Navy, 28 over 21, or the 28N. The 1928 Navy model, too, was made from a standard 1921A model. It was conceived because of the U.S. Military’s desire to have the rate of automatic fire reduced from 800 rounds per minute to approximately 600 rounds per minute. This was accomplished by redesigning the actuator by adding a block of steel to it. This made the assembly four ounces heavier, and along with redesigned recoil spring and pilot rod, slowed the rate of fire to an acceptable level. The firing pin spring was also redesigned and was slightly shorter than in the 1921 model. All 1928 Navy models had the numeral 1 (in the 1921 designation) overstamped with the numeral 8 to make it read 1928. The words “U.S. Navy” were also stamped into the receiver on virtually all of the converted guns. The Navy markings were impressed into the receiver rather lightly and appear noticeably different from all the other receiver markings. Although the Colt 1928 “Navy” models were marked “U.S. Navy” few actually went to the United States Navy. It proved to be the most popular model and many “U.S. Navy” 1928s were sold to police departments and foreign governments.”

    One of the prettiest guns ever designed and built. Not to mention a damn fine firearm firing a very potent caliber for close in work. It may be heavy, it may have been expensive to produce but it is beautiful to look at. This particular example is one of the sexiest I’ve seen in a long time. The bluing is excellent, the wood is exquisite, a nice dark walnut. Wish I could win that damn lottery so I could get one of my own. Oh well dreams are nice to have. If we had everything we wanted life would become boring but I would like to find out how boring being filthy rich could be.

    Sweet! What’s not to love? Classic looks, classic sound. It’s so, so, Gangsta.

    Nice weapon, but I prefer the M-3 ‘Grease Gun’. Lighter, simpler, handier in the jungle/ close quarters. I sure would like to have that one though ! 🙂

    It was uncommon for the Navy to have Thompsons with a vertical foregrip, although some folks, notably police departments, added them to surplus M-1928 and M-1 Thompsons after the war. Now, having used one on my AR, I can see why. Enjoy shooting it. A lot of fun, but will burn up ammo quickly.
