It fired .45 ACP cartridges at about 850 rounds per minute. The model 1921AC, which came out in 1926, featured a Cutts Compensator, a muzzle brake, which helped prevent the muzzle from rising during automatic fire."

Even so-called light machine guns could not easily be handled by single soldiers. To meet the need for an individual rapid-fire weapon, several inventors devised submachine guns. Light enough for one-man use, the new weapons were nicknamed \"trench brooms\" because they swept the trenches clear of enemy troops. The Thompson submachine gun was the handwork of John Taliaferro Thompson (West Point Class of 1882). It saw only limited wartime use, but the \"Tommy gun\" in the hands of police and gangsters achieved notoriety as \"the gun that made the twenties roar.\""

This submachine gun evolved out of the MP38, which was prone to misfirings that had sometimes lethal results. A simple technical innovation to the hammer eliminated the problem, and the MP40 was born. Total production is unknown but it is believed that more that one million of these weapons were produced between 1940 and 1944."
