The M1A1 Thompson submachine gun on display at the Virginia War Museum. The M1A1, standardized in October 1942 as the United States Submachine Gun, Cal. .45, M1A1, could be produced in half the time of the M1928A1, and at a much lower cost. The main difference between the M1 and M1A1 was the bolt.
In firearms, a blowback system is generally defined as an operating system in which energy to operate the firearm's various mechanisms, and automate the loading of another cartridge, is derived from the inertia of the spent cartridge case being pushed out the rear of the chamber by rapidly expanding gases produced by a burning propellant, typically gunpowder.

Thompson studied several designs and was impressed with a delayed-blowback breech system designed by John Blish, a commander in the United States Navy. With Blish as a partner, Thompson obtained the necessary venture capital to form the Auto-Ordnance Company, and began working on the design of what eventually became the Thompson submachine gun. [4]
