Perhaps one of the most oddly designed firearms of the modern era is the STEN submachine gun. STEN is an acronym used to describe a family of British submachine guns originally designed in 1940 and used by the United Kingdom and the Commonwealth of Nations during World War II and the Korean War.

Named for its chief designers, Major Reginald V. Shepherd and Harold Turpin – with an added "EN" for Enfield – the STEN submachine gun is a blowback-operated submachine gun that fires from an open bolt. While this is not very odd itself, the choice for a side-mounted magazine most definitely is, as it brought about a number of reliability concerns.

The STEN magazine was a direct copy of the MP-38 magazine, which means that the STEN magazine carries its faults alongside its design. Dirt and foreign matter? Say goodbye to reliability. Using the magazine as a support-hand grip? Say goodbye to your precise eight degree feed angle. All that really matters, though, is that you can own a lovely reproduction of this less-than-stellar magazine by purchasing the STEN magazine today.

Manufactured from premium raw materials in a production facility that holds several foreign military contracts, the STEN magazine is designed to hold and feed 32 rounds of 9x19mm Parabellum ammunition to your STEN submachine gun or any of its numerous variants. It is also compatible with the MPA-30.

The STEN magazine is now available in our web store.

More often than not, original, factory-produced magazines are better suited for firearms than are aftermarket magazines. As such, it is beneficial to seek out these original, factory-produced magazines, as they are manufactured by the same company and to the exact 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 surplus firearms like the STEN and its many variants that are still viable can sometimes prove both difficult and expensive. But when the alternative is a brand magazine, then you have absolutely nothing to worry about.

Each magazine, including our brand new STEN magazine, 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 – a goal that took several years to reach with this particular magazine. 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 produce is rigorously field tested to ensure proper fitting, feeding and ejection. Not to mention, our magazines are manufactured using premium raw materials alongside modern manufacturing technologies. 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 STEN magazine is a detachable box magazine that boasts a familiar design based on the original military STEN magazine. As such, these magazines are guaranteed to fit and function reliably in any STEN submachine gun, including the STEN Mk I and each of its many variants. This magazine is also compatible with the MPA-30. The body of the magazine, which is designed to hold and feed 32 rounds of 9x19mm Parabellum ammunition to your firearm, is constructed from hardened steel that has been fully heat treated. It also boasts a black Teflon®-based finish for enhanced protection against rust and corrosion. Additionally, both the steel spring and follower are precision manufactured to provide for reliable feeds on a consistent basis.

Note: The STEN magazine is a reproduction of the original STEN magazine, which was a direct copy of the MP-38 magazine. As such, it may still suffer from the reliability issues characteristic of the original design, as our modern manufacturing techniques are not capable of correcting inherent design flaws. If properly maintained, your STEN magazine should perform well.
