Why Did America Replace the Legendary Thompson?

Why did America replace the legendary Thompson submachine gun during World War II? Known as the “Tommy Gun,” the Thompson became one of the most recognizable firearms of the 20th century. First developed after World War I, it gained fame during the Prohibition era before serving American troops during World War II. But behind its legendary reputation were serious disadvantages. The Thompson was heavy, expensive to manufacture, and increasingly difficult to justify when the U.S. military needed weapons in enormous quantities.
