Auto-Ordnance Thompson 1927A1 Deluxe .45 ACP 18in 10+1
Pros & cons
What works
- Uses a machined 4140 steel receiver — authentic to the original material specification and far more durable than cast replicas.
- Features a 1-in-16 inch twist rate barrel — optimized for stabilizing standard 230-grain .45 ACP rounds within 50 yards.
- Weighs 13 lbs (5.9 kg) — delivers the authentic, heavy handling feel of the original firearm for immersive shooting.
- Includes American walnut buttstock and foregrip — provides correct period aesthetics without needing aftermarket upgrades.
Trade-offs
- Drum magazine requires specific loading procedure — takes approximately 90 seconds to fully load 10 rounds compared to 10 seconds for a box magazine.
- No optics mounting solution — the solid top receiver prohibits red dot or scope installation without significant gunsmithing.
- Field stripping requires a drift punch — disassembly for basic cleaning is more involved than a modern takedown pin system.
- High ammunition cost — training with commercial .45 ACP averages $0.50 per round, nearly double the cost of 9mm.

About this product
What is the Auto-Ordnance Thompson 1927A1 Deluxe .45 ACP 18in 10+1? This is a semi-automatic replica of the historic Thompson submachine gun, configured to avoid NFA Title II restrictions by using a 16-inch receiver extension and a permanently pinned compensator to achieve its 18-inch barrel length and 41-inch overall length, specifically designed for collectors and recreational shooters who want the iconic look and handling of a Tommy Gun without the federal paperwork. It reproduces the external handling characteristics and mechanical operation of the original, but in a legal, semi-automatic-only format chambered in readily available .45 ACP ammunition that feeds from a modern reproduction 10-round drum magazine.
What is the Auto-Ordnance Thompson 1927A1 Deluxe used for?
This firearm is used exclusively for recreational shooting, historical display, and as a collector's piece for its period-correct aesthetics. You will not find practical competition or defensive applications for this 13-pound, 41-inch carbine; it is a range toy and a conversation starter, best suited for controlled bench shooting or as the centerpiece of a World War II-era collection where its solid-steel construction and American walnut furniture can be appreciated.
How does the Auto-Ordnance Thompson 1927A1 Deluxe compare to the Stevens 334 Rifle?
The Thompson is a fundamentally different firearm, serving historical and aesthetic purposes where the Stevens 334 in .308 Win is a modern, practical tool for hunting and precision shooting. The Stevens 334 rifle is better at putting rounds on target at distance with its modern bolt-action design and lighter 7.2-pound weight, while the Thompson is superior at creating an immersive historical shooting experience and drawing attention at the range due to its iconic silhouette and unique 10-round drum magazine.
What does it weigh and what are the dimensions?
The 1927A1 Deluxe weighs a substantial 13 pounds (5.9 kg) unloaded and measures 41 inches (1041 mm) in overall length. Its barrel features a 1-in-16 inch twist rate and is 18 inches long, which includes the finned section and a permanently attached compensator; the width across the horizontal walnut foregrip is a distinct 3.5 inches, making it a notably wide and heavy firearm that requires a solid shooting bench or a strong supporting hand.
Who is this NOT for?
This is not for the shooter seeking a practical, lightweight, or affordable carbine for defensive use or hunting. If your priority is modern ergonomics, accessory mounting, ammunition cost per round, or ease of field-stripping for cleaning, you should look at a contemporary pistol-caliber carbine like those from Ruger or Kel-Tec; the Thompson's 13-pound weight, manual of arms, and niche magazine system make it a purpose-driven purchase for a specific type of enthusiast.
What's in the box?
You receive the complete rifle, one 10-round drum magazine, and a basic owner's manual covering safety and operation. Do not expect a case, cleaning kit, or any spare parts; this is a no-frills presentation focused on the firearm itself, so budget an additional $50-100 for a suitable hard case for transport and proper storage solutions to protect the walnut finish.
Is the Auto-Ordnance Thompson 1927A1 Deluxe worth it at $1,776.99?
At this price point, it is worth it only if you specifically value owning a functional piece of firearm history with correct materials and heft. You are paying for the machined steel receiver, American walnut furniture, and the licensing and tooling to produce an accurate semi-auto replica, not for modern performance; compared to a far more practical modern rifle like the Stevens 334 in .308 Win costing roughly half the price, the value is entirely subjective and tied to the collector's premium.

Frequently asked questions
- Are original Thompson parts compatible with this reproduction?
- No, internal parts are generally not cross-compatible with original military-issue full-auto Thompson guns due to design changes for semi-automatic-only operation. However, some external furniture like vertical foregrips may fit, though you must ensure any modification does not violate the 16-inch minimum barrel and 26-inch overall length requirements to avoid creating an unregistered NFA item.
- Does this ship with the drum magazine inserted?
- No, federal regulations require the firearm and magazine to ship separately to the FFL. The 10-round drum magazine will be included in the shipment but packaged disassembled and not attached to the firearm; expect a 10-15 minute assembly process following the included instructions before your first range trip.
- Can the compensator be removed for a suppressor?
- No, the compensator is permanently pinned and welded to the barrel to achieve the legal 18-inch barrel length. Removing it would reduce the barrel below 16 inches, creating a Short-Barreled Rifle (SBR) requiring a $200 tax stamp and ATF Form 1 approval; this is a factory-configured, non-NFA item designed to stay that way.
- How long does delivery take once ordered?
- Expect processing and shipping to your selected FFL dealer to take 5-7 business days after order verification. This timeline is standard for Ironclad Armory's specialty firearm transfers and includes the mandatory compliance check before the carrier pickup.
