Auto-Ordnance Thompson T5100D 1927A-1 | .45 ACP

The Auto-Ordnance Thompson T5100D 1927A-1 is a semi-automatic .45 ACP carbine that reproduces classic Thompson styling with modern production methods. This configuration pairs a blued metal finish with an American walnut stocked grip and includes both a 20+1 stick magazine and a 100+1 drum magazine for high-capacity use. For optics, a low-power variable such as the Vortex Viper PST 1-4×24 fits under $1,000 and offers quick target acquisition for close-to-mid-range shooting while maintaining a low mounting profile.

Applications include historical-style collecting and range-oriented recreational shooting. The rifle is built to present period-correct aesthetics while functioning in a contemporary semi-automatic format.
