If I could interject a question about S&W made PPKs, Smith & Wesson has never had a reputation for making bad guns, mostly. Why the bad reputation for the PPKs and PPK/Ss they make? In fact, do they not make them for Walther now?
Highly ironic, exporting Walther pistols to Germany from the United States.
I have both a Sig 232 and SmithWalther PPK/s. The 232 is used and is a great gun, I really enjoy it!
I got the SmithWalther new, had fail to feed and fail to extract issues, had the LGS send it to Smith. Smith reported no problems and sent it back dirty.
Problems persisted, sent back to Smith, Smith reported no problems, sent it back dirty.
Went to my LGS and swapped for another PPK. Had problems. LGS let me trade it in at full value for any other gun and I got a Smith airweight .38.
A while later another crop of PPK/s s surfaced, so, foolishly I tried again. Cleaned it at the store and shot it at their range. In 30 rounds a trigger assy pin started drifting out. Returned the gun.
A while later, the bug hit again, the LGS had another crop in, and I got one. This one has worked perfectly.
So, to your question: With no knowledge on the topic, I THINK part of the issue is the SmithWalther was built under license, and Smith, with an American Not Invented Here attitude, just never gave a damn about the PPK.
I would love a German PPK in .32, but cheap now they are not. But my SmithWalther is a good weapon and I can live out my inner-Bond with it. The Sig 232 is a better weapon.
Oh, last time I checked, Walther was going to build the PPK again in the US, along with some other models. I THINK those plans are still on track, but won't swear to it.
