Tommy Gun Goes Lightweight with the Auto-Ordnance TM1CP

Auto-Ordnance has announced the Thompson TM1CP, a lightweight take on the iconic M1 Thompson chambered in .45 ACP. Dubbed the Lightweight M1 Thompson, the new model carries the same recognizable silhouette that made the original "Tommy Gun" famous while shedding a significant amount of weight for the modern shooter.

The key changes involve swapping out the traditional steel receiver and wood furniture for a high-strength aluminum alloy receiver and simulated American walnut polymer furniture. Auto-Ordnance says this combination drops roughly five pounds from the gun's overall weight, which the company claims represents a 34.8% reduction compared to the standard steel-and-wood TM1 model.

The result is a 7.5-pound carbine that retains the period-correct aesthetic while offering less fatigue on long range days, if that is a thing with the M1?  The lower materials cost also translates to a more accessible price point compared to the traditional variant.

The TM1CP has a 16.5-inch smooth barrel, 38 inches of overall length, and fixed sights consisting of a pinned front blade and a fixed battle rear. The carbine comes standard with one stick magazine and is offered in two configurations: the TM1CP with a 30-round stick, and the TM1CP10S with a 10-round stick for buyers in capacity-restricted jurisdictions.

Auto-Ordnance also notes that Thompson is prohibited in Connecticut, Maryland, and New York. I’m thinking, so the Chicago Typewriter would still be available there?

For collectors who want the Tommy Gun experience without hauling around a steel-framed safe queen at the range, the TM1CP makes a practical argument. Chambered in .45 ACP, it will still hit hard. The MSRP comes in at $1,246 and a one-year warranty is included.


Specs:

  • Caliber: .45 ACP
  • Barrel: 16.5" smooth
  • Overall length: 38"
  • Weight: 7.5 lbs (without magazine)
  • Receiver: Aluminum alloy
  • Furniture: Walnut-grain polymer
  • Sights: Pinned front blade, fixed battle rear
  • Magazine: 30-round stick (TM1CP) or 10-round stick (TM1CP10S)
  • Prohibited in CT, MD, NY

Would you trade traditional wood and steel furniture for a lighter, more affordable Thompson, or does the classic construction matter too much to you?

    I'm stumped. I have a 1993 Numrich made M1 Thompson carbine with an empty weight of 8.25 pounds, but the website claims they weigh over 11 pounds. It's possible my mind is playing tricks on me, but when I bought it I thought it was a lightweight model, though all the sources I can find online claim the 1927A1 was the only lightweight version offered back then.

    How about a factory installed FRT?

      Just getting them to work with the regular fire control parts is hard enough, but I understand your desire.
