There's really nothing else that looks like a Thompson with a drum magazine attached. It's one of the most recognizable silhouettes in firearms history, and Auto-Ordnance built this 10-round drum to preserve every bit of that. Made entirely in the USA to match the original specifications, the T12BKT gives your 1927-A1 the look it deserves without sacrificing reliability.
Construction is all steel with a blued finish, measuring 6.75 inches in diameter, the same as the period-correct originals. Inside, a rotary feed system driven by a high-strength steel spring and polymer follower keeps rounds tracking smoothly and consistently. No gimmicks, no shortcuts, just a well-built factory magazine that functions as good as it looks.
This drum is built specifically for modern Thompson 1927-A1 long guns manufactured in Worcester, MA. It will not fit older Thompson firearms made in West Hurley, NY, or any Thompson built before 1990, and it does not fit the Thompson M1 military-style model with a side-charging handle. If you're unsure which Thompson you have, check the receiver markings for the Worcester, MA address.
The drum ships with a third-hand installation device, which is a small but genuinely helpful tool that makes the loading and assembly process much easier. Anyone who has wrestled with a drum magazine without one will appreciate it being included right in the box.
This drum is designed for modern Thompson 1927-A1 long guns made in Worcester, MA by Auto-Ordnance. It will not fit Thompson firearms manufactured in West Hurley, NY or built before 1990. It also does not fit the Thompson M1 military-style model. If your receiver says Worcester, Massachusetts, you're good to go.
The third-hand is a small tool included specifically to help with loading and installing the drum magazine. Drum mags require a bit more finesse than stick magazines during assembly, and the third-hand makes the process much easier and less frustrating. It's a nice touch that Auto-Ordnance includes it right in the box rather than making you track one down separately.
Yes, Auto-Ordnance is the original manufacturer of the Thompson submachine gun, and these drum magazines are made entirely in the USA to match the original specifications. Since 1999 the brand has been part of Kahr Arms, which has continued to maintain the historical accuracy and quality of the product line.
The drum uses a rotary design where rounds are stacked in a spiral pattern inside the drum body and fed upward by a high-strength steel spring with a polymer follower pushing rounds into the feed path. When you load it, you wind the spring to the correct tension, which is why the installation device is helpful. The design is true to the original and feeds consistently when properly wound.
It works well for both. The blued steel finish and exact-spec dimensions give it the authentic appearance that collectors want, while the steel construction and reliable internals make it plenty capable on the range. For anyone who owns a Thompson 1927-A1 and wants the full classic look and experience, the drum is really the defining accessory.
