I own a PPK/S .22 LR as well as a Walther PP in 22LR (the British contract L66A1 version), and a Beretta 71 for comparison purposes.
If you look at the trigger connector arm on the PPK/S .22LR and the PP in .22 LR you'll note the finish isn't quite as good, although they are constructed the same way.
You'll also note the barrel on the PPK/S .22LR is a bit different, installed in a shroud that is pressed into the frame, while the PP has the barrel pressed directly into the frame.
In all other respects it's very much a PP series pistol.
A second major difference is a much improved magazine design with a better feed angle and more stagger in the single co,u,n magazine that helps prevent rim lock.
Umarex Walther also made up for the lighter frame material by filling in the area around the magazine and under the grips. It gives it a weight very close to the .380 ACP PPK/S.

I've owned mine since 2014 and it's proven to be just as accurate as my PP in .22LR and it's proven to be much more reliable. I really enjoy shooting it, although the DA trigger is a bit heavier than the already heavy trigger on the other PP series pistols.
It's also not very particular on ammunition, provided it's high velocity ammunition. It's one of the few semi autos I have that will feed Remington Thunderbolts.
