Historcal Jamming PPK

[Andyd]

I have tested a few dozen Walther PPs in .32 ACP, .380 ACP, and .22 l.r. in the last couple of years and have not had one single malfunction with the .32 and .380 ACP with Magtech ammo. The .22 l.r. version is a little bit more finicky and depends on the right ammo. When Walther built the first .22 l.r. PPs in the mid 1930s they used a slide that had lightening cuts inside. Post war guns do not have these cuts and depend on HV ammo for proper functioning. Walther PP and PPk's, as well as HK4s, were designed to work with HV ammo and RWS HV was the ammo they were tested with. I have about 20 different PP rimfire mags and noticed that while they might work perfectly in one gun, they won't in another.
I just checked a Walther PP L66A in .22 l.r. a couple of weeks ago and the gun had the occasional hick up with SV ammo.

Walther did not restart production in W. Germany until the 1950s.

Walther resumed firearm production in late 1952, when smoothbore firearms could be produced again. Before that the new factory in Ulm manufactured mechanical calculators. My dad had one in his office and the calculator, as well as its dustcover, had the Walther banner. Mauser made steel office furniture.
