Walther PP .22 conversion

[Pofoo]

Has anyone ever heard of converting a PP (or ppks) to .22lr?
Ideally, a slip in barrel kit that is easily installed and removed would be best.

I have a PP in .22lr and the obvious changes are the barrel, magazine, recoil spring and a lightened slide. There are probably other less obvious changes like the feed ramp and possibly the magazine well. If you run across one in .22 I highly recommend it, it's delightful. There are conversion kits but they look weird and rare.

You would also need a slide fitted for 22s.

.22LR would require the firing pin to be moved to a rim fire position.

The best gun for this type of swap was the H&K HK4.
This gun had a removeable breech face to allow changing from center to rimfire firing pin positions and back again.

From what I've seen, conversion kits are the complete slide and barrel. Not only because of different barrel to slide fit, but also because of the firing pin as ojisan mentions above. These kits are hit or miss and their cost is high enough that you should consider just getting a dedicated 22 instead.

Messing with individual pieces such as breach face is a pain. I have a 40/9 conversion on my SVI Limited that includes fitted barrel, different breach face and different extractor (although I run 9mm extractor on my .40 setup) and I have *never once* used it because I don't want to mess with the breach face screws and Loctite. If I do it, it will be a semi-permanent long term change to 9 (if I quit Limited and start shooting just Open and C/O).

I too own a Walther PP in 22lr (1969)---I highly recommend it---a wonderful little pistol... I honestly have my doubts about converting a larger PP into a 22lr---just too many changes needed to make it function well...
I also own a Swiss SIG P210-2 9mm with a a factory 22lr conversion unit---this is done right with a whole new top-end---slide, barrel, recoil spring and dedicated magazine... It works very well and was very expensive (as is everything P210), but is picky about which ammo it will run with---in this case, only CCI Mini-Mags or CCI Blazers run 100% of all the 22lr ammo types I have tried, but that's OK as I have a bunch of that ammo...
I know original Walther PPS and PPKs in 22lr are costly, but amazing little pistols and a lifetime investment, but I don't think 22 conversions are the answer here because the barrels are fixed to the frame on these pistols---good luck!
