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.
Some authorities, such as Julian Hatcher, felt the Blish lock as employed in the submachine gun did not accomplish much in terms of actual breech locking. In fact, the submachine gun was successfully redesigned as a simple blowback weapon (the M1/M1A1). Any real advantages to the system were far outweighed by the additional cost of manufacture ...
Auto-Ordnance Corporation was created by John T. Thompson in August 1916 with the backing of investor Thomas Ryan. In 1915 Thompson had found the Blish Lock patent of Commander John Blish, which was the operating principle of the first prototypes of the Thompson submachine gun and the Thompson Autorifle. In exchange for shares of the newly ...

A Mini Uzi and a Heckler & Koch MP5K, two common submachine guns. A submachine gun (SMG) is a magazine-fed automatic carbine designed to fire handgun cartridges.The term "submachine gun" was coined by John T. Thompson, the inventor of the Thompson submachine gun, [1] to describe its design concept as an automatic firearm with notably less firepower than a machine gun (hence the prefix "sub-").
Thompson was shot in the back and taken to Mount Sinai West, at 10th Ave. and 59th St., which some New Yorkers still call Roosevelt Hospital, where he was pronounced dead.
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.
