The PPK was my grail too. After hitting the store with cash in my pocket, I was a little less than impressed with the S&W version of the PPK. Still nice, but not what I thought it was going to be.
While looking at the PPK, I stumbled across a Walter PPS 9mm and was smitten. It is of course a Walther and, it is a Walther that was actually made by Walther in Germany. After a little internal debate, the PPK lost to the PPS. I have not regretted the decision. It is accurate and reliable.
I might suggest that if you want a PPK, why not hold your money back and buy when Walther ends their partnership with S&W? That way you will end up with a German made Walther. If you can't wait, take a look at the PPS, it just might surprise you.
