Kahr Arms Auto-Ordnance Thompson Long Gun Drum Magazine .45 ACP 10/rd

The Kahr Arms Auto-Ordnance Thompson Long Gun Drum Magazine .45 ACP 10-round is a purpose-built feeding system designed for modern Thompson-pattern rifles and carbines chambered in .45 ACP. Originally inspired by the legendary Thompson submachine gun's drum configuration, this magazine serves shooters who demand reliable ammunition capacity in tactical, recreational, and historical-reproduction platforms. The drum design provides a compact footprint while maintaining the ten-round capacity mandated by federal law, making it ideal for both sport shooting and duty applications where magazine changes must be minimized.

Built to Kahr Arms' exacting standards, this magazine features precision-formed construction that ensures consistent feeding reliability with factory .45 ACP ammunition. The drum's spiral feed lips and internal geometry are engineered to prevent jamming and double-feeds, critical factors in any rifle-length platform where feed failures impact mission effectiveness. Weighing 2.55 pounds when fully loaded, the magazine balances capacity against weapon balance—essential for accurate sustained fire or tactical transitions. The robust construction withstands repeated loading cycles and maintains dimensional integrity across temperature variations, ensuring performance in the field.

This magazine is fully compatible with Kahr Arms Auto-Ordnance Thompson long guns and other .45 ACP drum-fed platforms using Thompson-pattern magazine wells. Law enforcement and military personnel, as well as civilian shooters operating Thompson carbines, benefit from the increased round count and reduced reload frequency during extended training or competition scenarios. Installation is straightforward—insert the magazine into the Thompson platform's magazine well and rotate or lock according to your specific firearm's design. For optimal performance, inspect the magazine regularly for dirt or debris and store away from extreme heat to maintain feed reliability.
