The German submachine gun EMP (Erma Maschinenpistole) also known as MPE (Maschinenpistole Erma) was produced by the Erma factory, and was based on designs acquired from Heinrich Vollmer. The gun was produced from 1931 to 1938 in roughly 10,000 copies (in three main variants) and exported to Spain, Mexico, China and Yugoslavia, but also used domestically by the SS. It was produced under license in Spain by the arsenal of A Coruña under the designation M41/44.
