Auto-Ordnance M1 Thompson .45 ACP

Read Gun Tests Rating and Recommendation

Gone is the Cutts, the drum magazine, and the forward pistol grip of the early Thompson design. This M1 is all business, and 2.5 pounds heavier than the other example tested. Well made and good looking, this one performed well also.

We had almost no problems with the M1. One round failed to chamber, early in our testing. We could not tell if the round had hung up on the chamber or if the extractor had failed to slip over it. It never happened again. The M1 handled the hot Cor-Bon ammo easily. As noted, the sight setup would permit filing down the front sight to get elevation where you want it with your best load. Accuracy of the M1 was okay, on the order of 3.5 to 4 inches at 50 yards. We would have liked more. The overall weight of 11.5 pounds might be a bit much for all-day offhand work.
The side-mounted bolt knob made this one a shade easier to handle, but the well-machined, all-steel receiver gave it a lot of weight it didnt really need.
The rear sight was not adjustable, but had both an aperture and long-range notch at its top. The sight blade was formed from the same piece of metal that formed the protective ears. Simple and rugged.
The M1s sight picture was perfect.
