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

The Auto-Ordnance 1927A-1 Lightweight Deluxe .45 ACP 16.5" rifle represents the modern evolution of one of America's most iconic submachine gun designs, now chambered in the proven .45 ACP cartridge for civilian and professional use. This semi-automatic rifle platform serves law enforcement trainers, civilian shooters, and tactical enthusiasts who demand reliable, high-capacity firepower in a compact package. Built on the legacy of the original Thompson submachine gun platform, the 1927A-1 delivers authentic handling characteristics with modern manufacturing standards and regulatory compliance for civilian ownership.

The Lightweight Deluxe configuration reduces overall system weight to 26.6 pounds, making it more maneuverable than earlier variants while maintaining the robust .45 ACP ballistics that have proven effective in duty use for over a century. The 16.5-inch barrel length optimizes velocity and accuracy while keeping the overall profile compact—at 42.5 inches total length, it handles efficiently in confined spaces, vehicles, and tactical training scenarios. The 100+1 capacity refers to the standard 100-round drum magazine with one round chambered, providing sustained firepower for extended engagements without immediate reloading. Semi-automatic operation ensures full legal compliance across jurisdictions, while the Thompson receiver design maintains the crisp trigger control and ergonomic safety lever positioning that operators expect.

This rifle excels for law enforcement training courses, civilian tactical training, and home defense scenarios where .45 ACP's proven stopping power and low-velocity performance make it ideal for barrier-blind situations. The Auto-Ordnance 1927A-1 accepts standard Thompson-pattern magazines and components, making ammunition and spare parts readily available through standard commercial channels. Operators familiar with original Thompson designs will appreciate the ergonomic consistency, while new shooters benefit from the lightweight design reducing fatigue during extended range sessions or training evolutions. Magazine compatibility and the drum option provide flexibility for various operational profiles, from precision accuracy work to rapid-fire tactical scenarios.
