The MP58 was a West German prototype submachine gun designed by ERMA Werke.
History[]
After the Bundeswehr's rejection of the MP57, Erma received funding and assistance from the Federal Ministry of Defense to design a new, cheaper submachine gun. The resultant weapon was the MP58. It was built to the Bundeswehr's specifications and was tested in early 1959, but was rejected with recommendations for improvements. Erma then developed an improved version of the MP58, named the MP59.
Design[]
The MP58 was a conventional blowback design with a telescoping return spring. It was constructed largely from sheet metal stampings and the layout was closely based on the MP40, including a similar folding wire stock. It fed from MP40 magazines.
