FWIW:
Before I purchased my first P99/AS I did research on the Walther P99 pistol.. I used the "Google" function", and even tho you are an old fart, such as myself, I suggest you might consider doing the same for the PPS.
I was able to find sufficient information explaining the development and testing of the P99 to resolve any questions I might have had as to the quality and durability I could reasonably expect from the Walther P99 pistol.
Apparently the German Government has very strict standards when it comes to any firearm that is being considered for use by them. I believe NATO specs and requirements also come into play for any firearm that might be offered to them as a service weapon, but I'm not sure if that was a factor in the development of the PPS, as the PPS was not designed or intended to be a full service military/police type firearm.
My understanding is that the PPS was in fact designed to replace the popular, but aging PPK series of pistols. (Which are now in fact manufactured and sold by S&W).
I have NOT done the research for the PPS and do not intend to do so. I do, however, intend to buy a PPS which should indicate I expect the new PPS to be of equal quality to the P99. I have in fact read where the PPS was in many areas designed "from" the Walther P99c.
I'm way too old to spend my time researching this issue for you, and you are more than welcome to be a skeptic on the issue, I have no problem with that.
I apologize if I'm a bit touchy regarding your skepticism, but if you think the PPS was designed by two ex-Nazi elves in the Black Forest over a long weekend I suggest you simply lack sufficient knowledge of the history and fine reputation of the firearms the Walther banner represents.
I have no interest in a long winded pissing contest with you regarding the quality of the PPS pistol, I just suggest if you want one, buy one, and if you don't want one, don't buy one.
I have yet to own or shoot a Walther firearm that was not of excellent quality, amazing accuracy, and I do not expect the new PPS to be any different.
Please have the last word, or a thousand words if you so chose.
