Description

The Auto-Ordnance Thompson TA510D 1927A-1 .45 ACP 10.5 inch barrel pistol is a semi-automatic reproduction of the classic 1927 model, built for shooters who value honest materials and period-correct handling.

Key Features

• Walnut Horizontal Foregrip & Stock – The oil-finished walnut furniture gives you a solid, comfortable hold that reduces fatigue during extended sessions. It matters because you want a grip that doesn’t slip and a stock that shoulders naturally.
• Blackened Aluminum Receiver – This lightweight alloy keeps the overall weight under 12 pounds while maintaining the classic silhouette. It matters because you can carry and shoulder the pistol without feeling like you’re hauling a safe.
• 10+1 Drum Magazine (U.S.-Manufactured) – The included 10-round drum feeds reliably and replicates the original look. It matters because you get authentic period styling with modern manufacturing tolerances.
• Fixed Blade Front & Adjustable Rear Sights – The front post stays put, and the rear sight lets you dial in windage and elevation. It matters because you can zero for your preferred .45 ACP load and keep it consistent.
• 10.5-Inch Barrel with Threaded Muzzle – The 1:16 twist barrel delivers stable .45 ACP ballistics, and the threaded muzzle (5/8-24) accepts compensators or suppressors. It matters because you can customize the muzzle profile for recoil control or sound reduction.

Who It’s For

This Thompson is built for the traditional shooter who wants a semi-auto pistol that handles like the original 1927A-1. It suits collectors, range enthusiasts, and anyone who appreciates the history of John Thompson’s design. If you prefer wood and steel over polymer, and you want a .45 ACP that turns heads at the range, this is your pistol.

Pros & Cons

• Pros: Authentic walnut furniture, reliable drum magazine, lightweight aluminum receiver, adjustable rear sight, threaded barrel for accessories.
• Cons: The 10-round drum capacity is limited compared to full-size 50-round drums; the 10.5-inch barrel and aluminum receiver can feel muzzle-heavy until you add a compensator. The fixed front blade may need a file for precise elevation adjustment.

FAQ

Does the Auto-Ordnance Thompson TA510D accept standard Thompson drum magazines?

Yes. The TA510D uses the same drum magazines as the original 1927A-1 and the modern Auto-Ordnance M1 models. The included 10-round drum is U.S.-manufactured and functions reliably. You can also use aftermarket 50-round drums, but they may require a spring adjustment for consistent feeding.

Is the barrel threaded, and what thread pitch does it use?

Yes, the 10.5-inch barrel is threaded 5/8-24. This allows you to attach compensators, muzzle brakes, or suppressors. Per Auto-Ordnance specs, the barrel is machined from 4140 steel with a black oxide finish.

Can I change the sights on this pistol?

The front sight is a fixed blade dovetailed into the barrel. The rear sight is adjustable for windage and elevation. You can replace the front with a different blade height, but the dovetail is proprietary to Auto-Ordnance. The rear sight can be swapped with aftermarket units that fit the Thompson base.

Is this pistol legal in all 50 states?

The TA510D is classified as a semi-automatic pistol with a 10-round drum, so it complies with most state magazine capacity laws. However, some states (e.g., California, New York) have specific roster or feature restrictions. Check your local laws before ordering. We ship nationwide but cannot ship to restricted jurisdictions.

How does the weight compare to a standard 1911?

At approximately 11.6 pounds, the TA510D is significantly heavier than a steel 1911 (about 2.5 pounds). The aluminum receiver and walnut furniture keep it lighter than a full-size Thompson rifle (which exceeds 13 pounds), but it is still a heavy pistol best suited for stationary range use or display.
