The receiver is marked Worcester, Massachusetts, indicating Kahr-era production, and carries the Thompson "bullet" trademark along with model markings reading "MODEL OF 1927 A1" and "THOMPSON SEMI-AUTOMATIC CARBINE." These factory rollmarks provide clear identification and connect the carbine to the Thompson lineage.
The 16.5-inch smooth, non-finned barrel is paired with a Cutts-style compensator that houses a pinned blade front sight. At the rear, a ladder-style adjustable sight provides a traditional sight picture consistent with Thompson carbines.
The rifle uses a blowback action in .45 ACP with a top-mounted actuator slot and knurled charging knob. Ejection is to the right side. A manual safety is fitted, aligning with the platform’s straightforward operating controls.
The exterior wears a matte gray finish over a receiver and barrel, complemented by black synthetic furniture. It has a fixed black synthetic stock with a 17.0-inch length of pull, a black textured synthetic pistol grip, and a horizontal ribbed synthetic forearm. A front sling swivel is mounted under the forearm for carry options.
Configured as a Title I carbine, this 1927A1 combines recognizable Thompson aesthetics with practical features and modern materials, resulting in a durable, easily maintained semi-automatic carbine.
