Auto-Ordnance 1927A-1 Lightweight Deluxe .45 ACP 16.5" 100+1 Rifle

The Auto-Ordnance T5P100D 1927A-1 Lightweight Deluxe .45 Cal semi-automatic rifle represents a faithful reproduction of one of America's most iconic firearms for modern shooters and collectors. Chambered in .45 ACP, this semi-auto Thompson provides law enforcement trainers, civilian sport shooters, and firearms enthusiasts with a historically accurate platform that maintains the legendary profile and ergonomics of the original 1927A-1 while meeting contemporary regulatory requirements. The 100-round drum magazine capacity—paired with a 20-round stick magazine—delivers substantial firepower for tactical training scenarios, competition shooting, or defensive applications where sustained fire capability matters.

Built with a machined aluminum frame and receiver, the T5P100D achieves its "Lightweight Deluxe" designation while maintaining structural rigidity essential for repeated .45 ACP cycling and the recoil impulse inherent to the caliber. The finned barrel with integral compensator reduces muzzle rise and felt recoil, improving control during sustained fire and follow-up shot speed—critical performance factors for tactical training and competition use. Genuine American walnut furniture and grip panels provide period-correct aesthetics alongside practical ergonomic shaping, while the fixed stock configuration ensures consistent cheek weld and sight picture alignment for precision shooting. At 26.6 pounds, the rifle distributes recoil impulse effectively and reduces fatigue during extended range sessions or training evolutions.

This configuration excels for shooters seeking a historically faithful yet fully functional semi-auto platform—from law enforcement training academies qualifying with iconic American designs to civilian competitors in vintage or open-class matches. The dual-magazine system (100-round drum and 20-round stick) accommodates both high-volume training scenarios and reload-discipline drills. Compatibility with standard .45 ACP ammunition ensures cost-effective practice and duty round availability through established supply channels. The T5P100D's 42.5-inch overall length and conventional rifle ergonomics suit standard shooting positions and tactical employment across indoor ranges, outdoor courses, and institutional training facilities.
