Auto-Ordnance Thompson 1927A-1 Deluxe .45 ACP, 10+1

The Auto-Ordnance Thompson 1927A-1 Deluxe .45 ACP, 10+1 is a semi-automatic reproduction of the iconic Chicago Typewriter, built for range work and historical collections. Chambered in .45 ACP, it delivers the same heavy steel heft, Cutts compensator, and horizontal foregrip that defined the original. This isn’t a safe queen—it’s a shooter that runs on nostalgia and .45 ball ammo, with a 10-round stick magazine that keeps things legal in most states.

Key Features

• Cutts Compensator – Reduces muzzle rise and keeps you on target during rapid fire, exactly like the original Thompson design.
• Horizontal Foregrip – Provides a stable, two-handed hold that distributes weight evenly, crucial for controlling a 13.6-pound rifle.
• American Walnut Furniture – Fixed stock and forend deliver a solid cheek weld and heat-resistant grip, no polymer flex here.
• Blued Steel Receiver – Durable finish that resists corrosion and maintains the classic look of a 1920s service weapon.
• Traditional Ladder Rear Sight – Adjustable for elevation out to 600 yards (though realistically, you’re ringing steel at 100-200 with .45 ACP).

Who It’s For

This Thompson is for the collector who also shoots—someone who wants the heft and history without the NFA paperwork. It’s also for the range-goer who wants a conversation piece that punches holes in paper with authority. If you’re building a WWII-era collection or just want to sling .45 ACP with style, this is your lane.

Pros & Cons

• Pro: Authentic feel and fit—steel and walnut, no shortcuts.
• Pro: Cutts compensator makes it surprisingly flat-shooting for a .45 ACP carbine.
• Con: At 13.6 lbs unloaded, it’s a heavy beast for long range sessions—plan your sling setup accordingly.
• Pro: 10-round magazine capacity is compliant in restrictive states while still offering a decent magazine change cadence.
• Con: Rear sight is period-correct but lacks windage adjustment; you’ll need to drift the front sight for zero.
