Quick Overview

The Thompson submachine gun, designed by John T. Thompson in 1919, is an American submachine gun that utilizes a blowback system of operation and gained notoriety during the Prohibition Era due to a number of its features that made it particularly appealing to mobsters. Among those features are its ergonomics, compact size, reliability, high rate of fire and the .45 ACP cartridges it so quickly spent. I have a feeling that those mobsters were also pretty fond of the iconic drum magazines that fed their "Chicago Typewriters."


Well, the cherishing of those drum magazines is not limited to long gone gangsters. We here at Keepshooting.com love them too. And that is exactly why we put our very own Thompson® compatible drums into production.


Our Thompson® compatible drum is a high-capacity magazine designed for use with any Thompson Model 1921, 1927, 1928 and many other current-production semi-automatic models. Each drum boasts a design based on the original World War II drum, and will hold and feed 50 rounds of .45 ACP ammunition to your firearm. Guaranteed to fit and function in any of the aforementioned models, these brand new drum magazines are a must-have accessory for any Thompson enthusiast who is looking to keep his or her originals in pristine condition.

Details

Ordinarily, I would advise firearm owners to seek out original, factory-produced magazines for their firearms rather than purchasing aftermarket magazines. Generally speaking, it is beneficial to seek out these original, factory-produced magazines as they are manufactured by the same company and to the exact same specifications and tolerances as those that ship with the firearms for which they are designed. Additionally, they are manufactured using the same materials, a provision which ensures both proper fit and function in your firearm. However, finding original factory-produced magazines for older firearms like the Thompson submachine gun can sometimes prove both difficult and expensive. But when the alternative is a Keepshooting.com brand magazine, then you have absolutely nothing to worry about.

Each Keepshooting.com magazine, including our Thompson® compatible drum, begins with a guarantee. Our goal prior to production is the manufacture of a magazine that is not only 100 percent functional, but also 100 percent reliable. As such, we guarantee the function and reliability of all of our house-brand magazines 100 percent. If for any reason you are unsatisfied with the performance of your magazine, it can be returned for a refund of the purchase price provided it is free from modification, damage and visible signs of usage or wear.

How can we offer such a guarantee? Prior to release, a random sampling of every magazine we carry is rigorously field tested to ensure proper fitting, feeding and ejection. Not to mention, our magazines are manufactured using quality materials alongside modern manufacturing methods. If this sounds expensive, that is because it is. But due to the number of magazines we have made, our prices are driven down and in turn passed on to you.

As noted, the Thompson® compatible drum is a drum magazine with a design that is based on the original WWII drum magazines. As such, each drum features a full steel construction and is designed to hold and feed 50 round of .45 ACP ammunition to your firearm. Additionally, the drum features a blued finish to protect against rust and corrosion.

    Tried mine in a recent production semi. No problems at all. Quality construction at half the price of alternatives. Have not had a chance to try on in a real Thompson, but even in a semi it burns through ammo fast.

    I received 2 more of these drums today they all tested at range flawlessly.
    I came back on this website -> keepshooting to buy the rest but I see they are out of stock , someone beat me to the punch.
    I built a 1920's 1930's gangster room with original pictures of dillinger , bonnie & clyde etc, and my 6 kahr non-working auto-ordance drums are displayed in shadow boxes on the walls. Its a shame I made the mistake of buying those drums from a store that will not take returns. Unreal I paid by check and not credit card si I can't even do a charge-back.,oh well ! keepshooting please get more of these !, I have 4 now and need a even bakers dozen!

    received my drum, it was well oiled and had to clean it up. I loaded and wound it Nine clicks and it feed every round. Unlike the Thompson AO drum I bought at twice the price.It also slides into the gun without force!

    I want everyone to know that if the drum says Auto-Ordance or Kahr with the bullet stamp its junk, learn by what i just went through, pure hell with expensive over priced tin wall hangers.
    took parts from 6 NEW Auto-Ordance drums into one to finally get a single cycle to function , Auto-Ordance absolutely no quality control, Kahr tests nothing just ships there junk. To much paint inside , needs polishing along with burr's .
    These drums here are the best, no problems right out of the box, good fit nine clicks, POOOW!

    When I bought my 1927 A1 Thompson, I was leary about using a drum magazine. I was concerned about jamming and weight. But, I decided to get this drum for my weapon and it is excellent both in weight and reliability. I have put a lot of rounds down range with this drum attached and it functions great. I would recommend it to any Thompson owner.

    I am so glad that I bought this 50rd drum instead of one from
    Thompson. The quality is perfect and you can't beat the price.
    And you can't beat the speedy service either. I ordered my drum
    on Friday and it arrived on Monday.

    I just took 1 of these to the range. It works perfectly no trouble at all. Went right into the gun no trouble. Finish was superior to thompson oem drum. Thompson oem drums had to be fitted by gunsmith before they would go in the gun. These look and work better than original thompson drums. They say on the drum 9 clicks And there is no mistake a click is a click on these drums.
    I would trade 3 of my thompson o e m drums for 2 of these any day.

    I was a little worried when I bought my 50 round drum for my 1927 Tommy gun that it wouldn't be as nice as the drums made by "Thompson," but I took the drum out shooting the day that I received it in the mail and it shot perfect!! definitely worth buying from keepshooting.com.
