Design & Build — Heritage Meets Modern Semi-Auto Engineering
The AUTO-ORDNANCE THOMPSON 1927A-1 DELUXE STI is a semi-auto rifle chambered in .45 ACP that honors the original Thompson silhouette while adding practical modern features. The rifle ships with a 16.5″ finned blued barrel and is also available in an 18″ option. The receiver is steel blued, lending durability and classic aesthetics that match the walnut furniture option. A black synthetic option is available for shooters prioritizing weather resistance.
Furniture and Controls
Furniture choices include walnut fixed stock, walnut grip, and walnut forend for that vintage feel; alternative black synthetic parts are available for a more tactical, low-maintenance setup. Controls are intuitive and mirror traditional rifle ergonomics—easy to index behind the wood or synthetic pistol grip while staying balanced for controlled follow-up shots.
Sights, Compensator, and Sling Mount
Open sights are practical and adjustable: a blade front sight and an adjustable rear sight give clear, quick sight picture at close to moderate ranges. The compensated barrel option reduces muzzle rise and helps tame the .45 ACP impulse, while a factory sling mount provides immediate utility for carry and retention. These features make the platform a usable, everyday rifle rather than a purely showpiece.
Magazine Options & Capacity
Out of the box the rifle includes one 20-round stick magazine and one 50-round drum magazine, giving users immediate flexibility. The Thompson accepts both stick and drum magazines of higher capacities, which is a defining characteristic for this platform and one reason it’s appealing for extended range sessions or scenarios where increased capacity is desired.
Magazine compatibility is central to how this rifle is used: the 20-round stick offers compact handling and fast reloads, while the 50-round drum provides extended shooting with fewer magazine changes. For owners who appreciate versatility, the ability to swap between these feed systems is a significant advantage.

.45 ACP — Performance and Practical Applications
The .45 ACP is a time-tested cartridge known for controlled subsonic performance and stout terminal energy at practical defensive distances. In this semi-auto rifle configuration, the .45 ACP is easy to manage thanks to the platform’s mass—this model weighs approximately 13 lbs—and the finned barrel/compensator options which further reduce perceived recoil. That makes it well suited for training sessions, close-range defensive drills, and recreational plinking where controllability and classic cartridge behavior are appreciated.
Recoil and Handling
At roughly 13 lbs and an overall length near 41″, the rifle’s mass absorbs a significant portion of felt recoil, allowing for follow-up shots without harsh muzzle climb. Combined with the option of an 18″ barrel for slightly improved ballistic consistency or a 16.5″ finned blued barrel for a compact footprint, shooters can select a configuration that matches their handling preferences.
Who This Rifle Suits
The AUTO-ORDNANCE THOMPSON 1927A-1 DELUXE STI is for collectors who value historical lineage, shooters who enjoy a heavy, well-mannered semi-auto in .45 ACP, and range enthusiasts who want a rifle that stands out while remaining practical. Law enforcement-style users and private citizens focused on home defense may appreciate the balance of capacity options and the rifle’s controllability. Its 41″ overall length and 13 lb weight mean it’s not a lightweight truck gun, but its presence and performance are deliberate and assured.
Value and Pricing
With a listed price around $2,271.60, this rifle sits in the premium segment of semi-auto .45 platforms. That price reflects the classic styling, included drum magazine, solid steel blued receiver, and quality furniture options—walnut or synthetic. For those seeking authenticity and modern reliability combined, it represents a targeted investment.
Final Take — Practical Classic with Modern Utility
We appreciate firearms that balance legacy and usability. The AUTO-ORDINANCE THOMPSON 1927A-1 DELUXE STI delivers on both fronts: historical design cues, contemporary manufacturing, and practical features like included 20-round stick and 50-round drum magazines, adjustable sights, and optional compensator-equipped barrel lengths. If you want a semi-auto .45 ACP rifle that performs at the range, looks the part, and gives you magazine flexibility, this model warrants a close look.
