Auto-Ordnance Announces the New Lightweight M1 Thompson
Posted by Jodi DePorter on May 7th 2026
Auto-Ordnance is proud to introduce a modern evolution of a combat classic with the release of the Lightweight M1 Thompson. Chambered in the legendary .45 ACP, this new iteration retains the iconic silhouette of the original military workhorse while drastically increasing its portability and accessibility for the modern shooter.
By engineering the firearm with a high-strength, lightweight alloy receiver and simulated American Walnut polymer furniture, Auto-Ordnance has achieved a significant weight reduction of approximately five pounds. This makes the new model 34.8% lighter than the traditional steel-and-wood TM1, a design choice that provides the classic look of the "Tommy Gun" with the added benefits of reduced shooter fatigue and a more competitive price point.
Each Lightweight M1 Thompson is built to offer a perfect blend of historic legacy and modern performance. The firearm comes standard with one stick magazine and is available in either 30-round or 10-round capacities to meet various regulatory and user needs. Whether for a dedicated collector or a recreational shooter, the Lightweight M1 provides the unmistakable experience of an American icon in a package optimized for today’s range.
