The Thompson 1927A1M1 Tommy Gun in .45 ACP is an iconic semi-automatic rifle that demands reliable, authentic magazines to keep you in the fight. Whether you're running this classic at the range, in competition, or as a centerpiece of a vintage firearms collection, a spare 20-round stick magazine—or two—means you spend more time shooting and less time reloading. This factory replacement magazine is engineered to the same exacting specifications and tolerances as the originals, ensuring the fit and feeding reliability your Thompson expects.

Built from the same materials as genuine Thompson magazines, this 20-rounder delivers consistent performance across multiple generations of the platform. The stick-style profile is unmistakable and period-correct, and the detachable design makes loading, unloading, and storage straightforward. Anyone who has owned a Tommy Gun knows that quality magazines are non-negotiable—cheap or worn mags turn a smooth-running rifle into a frustration generator fast.

Keep one loaded and one in your range bag. Reload drills are faster when your spare magazine is already at hand, and you'll never be caught short during a session. For owners of Thompson T1, T1B, T1SB, T1BSB, T5, T1-C, TA5, TM1, TM1C, or M1S models, this magazine is a drop-in fit with no modification required.
