maybe they can re-enginner a 22 pistol that doesn’t jam every 3 -4 rounds. I sent it back, twice, still unreliable.

to be fair, the other walther pistol I have runs fine.

I think the .22 is just out of the sweet spot for a blowback pistol (and it doesn't help that the .22 is a rimfire cartridge). The .32 and .380 could operate the blowback mechanism well.

There are a lot of carriers who like the PPK but don't trust the lethality of the .380 / 9mm Kurz round. While blowback works for 9mm and even .45 as per Hi-Point using a very large slide, I suspect the reengineering plans for the PPK are one or more of the following:

1. 9mm Parabellum / Luger using recoil operation with a floating barrel instead of continuing the blowback design. Purists may not like it but the younger generation wouldn't care.

2. 9mm Parabellum / Luger in a new blowback design that holds the slide in place just long enough to use 9mm Parabellum / Luger ammunition.

3. 9mm Parabellum / Luger in a new blowback design that sends some of the excess gas forward to allow use of a slide similar to the current one.

My PP shoots better than me. 5 shots in a quarter size hole at 20 feet. A 100 year anniversary model.
Walther is just going to make cheap plastic guns.

I had a PDP. Took it to the range twice and sold it. Constantly jammed. Heavy recoil. The only thing I liked about it was the laser.
