The Thompson M1A1 was a .45 caliber ACP, Blowback operated, semi/full automatic submachinegun with 20/30 round magazines. The Thompson had cyclic rate of 600 rounds per minute. It was mainly used in WWII, The Korean conflict ad Vietnam. The U.S. government liked the idea of the more potent .45 caliber ACP which is a main reason it was produced in the first place. It was supperior over the German MP40 that it usually faced. It had challenges with the FG42 and MP44. Sorry if this information isn't helpful but your question is unclear.
