Thompson Compatible 50-Round Drum
The United Defense Thompson Compatible 50-Round Drum is a steel drum magazine chambered in .45 ACP, built to feed the legendary Thompson 1927-A1 and other modern Tommy Gun platforms. Constructed from heavy-gauge steel with a deep blued finish, the drum measures roughly 6.75 inches across and faithfully reproduces the dimensions of the original WWII-era magazines. A traditional wind-up key drives the internal spring for reliable feeding through all 50 rounds. It's a must-have accessory for Thompson owners, collectors, and shooters who want maximum capacity and authentic Tommy Gun looks at the range.
