Walther began developing a modern stamped sheet metal SMG in the late 1950s, and it entered production in 1963. It was an open-bolt, simple blowback gun available in a short (MPK; 6.75” barrel) and long (MPL; 10.25” barrel) version. It was cheap and simple, but well thought out with a number of quite good features.
The standard design was just safe/full, but a semiautomatic selector position was available if desired by the client. An excellent safety sear prevented the bolt from bouncing open and firing, and the charging handle was both non-reciprocating and capable of also serving as a forward assist if needed. The sights were a bit too clever for Walther’s own good, with a 75m notch and a 150m aperture, both of which were not really great.
Faced with competition from contemporaries like the Uzi and MP5, the Walther never really became massively popular. It did get enough small and medium sized contracts (German police, South African police, Mexican Navy, Portuguese Navy, US Delta Force, etc) to remain in production until 1985 though. Overall a solid and reliable gun even if it failed to really stand out from the other options on the market.
