The Pro Mag Thompson 45 ACP 40-round drum magazine brings serious capacity to your Auto-Ordnance Thompson .45 ACP carbine. If you shoot competition, tactical training, or just love running high-capacity mags at the range, this drum transforms your Thompson from a historical reference into a practical, fun-to-shoot platform. The 40-round capacity means fewer reloads and more trigger time—exactly what you need when you're pushing rounds downrange.
Built for reliability, the drum housing is molded from a proprietary DuPont Zytel-based polymer engineered to handle the demands of repeated loading and firing. The injection-molded follower keeps rounds feeding smoothly, while the heat-treated stainless steel spring delivers consistent pressure cycle after cycle. It's made right here in the USA, which means the quality control and materials are held to real standards, not just cost-cutting minimums.
Drum magazines for the Thompson aren't as common as stick mags, so if you own a .45 ACP Thompson carbine and want to maximize fun and capacity, this is the straightforward choice. The black finish matches modern tactical setups while respecting the classic lines of the gun itself.
