Description
Few silhouettes in American firearms history are as instantly recognizable as the Thompson. The 1927A-1C Lightweight Deluxe from Auto-Ordnance captures all of that Roaring Twenties character, then trims a serious amount of weight off the original formula. The receiver and frame are machined from aluminum alloy instead of steel, and the furniture is walnut grain polymer rather than solid hardwood. The result is a Tommy Gun that comes in noticeably lighter than the traditional Deluxe models, which makes a real difference when you spend an afternoon at the range instead of just admiring it on the wall.
What Sets the 1927A-1C Lightweight Deluxe Apart
This is a semi-automatic carbine chambered in .45 ACP, fed here by a classic 20-round stick magazine. The 16.5 inch finned barrel wears a compensator up front, and between the muzzle device and the soft-recoiling .45 cartridge in a carbine-sized package, follow-up shots come back on target quickly. Sights are a pinned front blade paired with a fixed rear, simple and true to the vintage look. The polymer furniture carries a convincing walnut grain, so from a few feet away it reads as the real deal while shrugging off dings and weather better than wood ever will.
Range Day With a Piece of History
Shooting a Thompson draws a crowd, plain and simple. The 1927A-1C runs from a closed bolt like a modern carbine, so it is smooth and predictable to shoot, and .45 ACP ball ammo is easy to find just about anywhere. Auto-Ordnance recommends sticking with brass-cased ammunition in their Thompson long guns, which is worth remembering when you stock up.
Why Pick the Auto-Ordnance Thompson 1927A-1C
If a full-weight Thompson has always felt like more of a commitment than you wanted, this version solves that problem without giving up the iconic lines, the finned barrel, or the .45 ACP chambering. It is a natural fit for collectors, WWII and Prohibition-era history buffs, and anyone who wants a range gun that turns heads every time the case opens.

Frequently Asked Questions
How is the 1927A-1C Lightweight Deluxe different from the standard Thompson 1927A-1?
The big changes are the materials. The receiver and frame are machined from aluminum alloy instead of steel, and the furniture is walnut grain polymer rather than solid American walnut. That cuts several pounds off the traditional Deluxe, making it much easier to carry and shoot for long stretches while keeping the same classic profile.
What ammo should I run in the Thompson 1927A-1C?
Standard brass-cased .45 ACP is the way to go. Auto-Ordnance specifically cautions against steel-cased ammunition in their Thompson long guns, so save the budget steel case for other platforms. Quality 230 grain ball ammo tends to feed the most reliably in these carbines.
Will drum magazines work with this Thompson?
Yes, the 1927A-1C platform accepts Thompson-pattern drum magazines, and Auto-Ordnance sells 50-round L-drums and 100-round C-drums that fit. This particular package ships with one 20-round stick magazine, so drums would be an aftermarket addition. Just make sure any drum you buy is made for the semi-auto Auto-Ordnance guns.
Does the Auto-Ordnance 1927A-1C fire from an open bolt like the original?
No, it fires semi-auto only from a closed bolt, which is standard for modern reproduction Thompsons. The upside is a smoother, more predictable trigger experience and better practical accuracy than the originals. You still get the finned barrel, compensator, and all the visual character of the classic gun.
