The Walther P38 was adopted by Germany in 1938 as a replacement for the P08 Luger - not really because the Luger was a bad pistol, but because it was an expensive pistol. Walther began development of its replacement in 1932 with two different development tracks - one was a scaled-up Model PP blowback in 9x19mm and the other was the locked-breech design that would become the P38.

The initial prototypes look externally quite similar to the final P38, although the locking system went through several changes and the controls did as well. Several of the early developmental models used shrouded hammers.

In this video I will take a look at both initial "MP" pistols (the blowback and the locked breech), then the Armee Pistole (aka the AP) in its standard configuration and also a long barreled model with a shoulder stock, then the second Model MP, and finally the HP which was the commercial model of the final P38. In addition, I will check out a sheet metal prototype of the locked breech model form the very beginning of the development program.
