Frequently Asked Questions

What are the key features of the Auto-Ordnance Thompson 1927A-1?

The Auto-Ordnance Thompson 1927A-1 is a semi-automatic civilian version featuring a 16-inch barrel (or 18-inch with compensator), 20-round magazines, and dual sight systems including a notch rear sight and an adjustable flip-up peep sight. It is notably heavy, with weight concentrated towards the rear.

How does the Auto-Ordnance Thompson 1927A-1 handle recoil?

Despite being chambered in .45 ACP, the Thompson 1927A-1 has virtually no felt recoil. This is attributed to its significant weight, long barrel, and the presence of a compensator, making it feel similar to shooting a .22LR rifle.

What was the accuracy like with the Auto-Ordnance Thompson 1927A-1?

Accuracy with Winchester White Box 230-grain ammunition was inconsistent, with significant flyers observed at 100 and 200 yards. The reviewer noted potential issues stemming from resting the barrel on a shooting bag and the firearm's trigger characteristics.

What are the reviewer's thoughts on the trigger of the Thompson 1927A-1?

The trigger is described as old-school, very long, and heavy, with an estimated pull weight of around 10 pounds. This long, heavy pull makes precise target shooting more challenging, especially at longer distances.
