I am thinking that I want a Walther PPKs. I want a stainless one. I will never carry it, I just think I want one. I am aware that several companies have made them. I think I saw some negatives about the ones S&W made. Is there any consensus on which ones to buy or which ones to avoid? Thanks for any information.
I don't know about a consensus, but I can tell you what I like.
If you want a real classic, made in Germany, Earl's Repair Service, who has a huge inventory, still has original PPK and PPK/S models in both .32 and .380 new in the box, but from pre-1968 Gun Control Act. They are very pricey and I have never been able to afford one, however, if you want the "real deal" you can still get it.
Second choice for a collector type is an Interarms import. Third is the Interarms manufactured under license pistol. I have shot these before, but I have never had one of my own as it is a gamble trying to get one that is new- or near new-in-the-box.
While I have never had any malfunction with my S&W-made PPK, I like the new one being made by Walther Arms here in the US, so it had to go when I shot the new one by Walther Arms USA.
For shooting and carry, the new Walther Arms made in the USA is my choice. I had a stainless one, but got rid of it when the blue/black ones came out. The black one is more of a nitride finish, very corrosion resistant, but it is more of a flat, very business like finish.
So, the one I have now is my favorite. The Walther Arms USA model with the black finish.
Also, I have come full circle on the issue of PPK versus PPK/S. The PPK/S with flat magazine is not appreciably bigger (taller) than the PPK with the thumb-rest magazine, and I prefer the extra round, so the PPK/S is now my favorite. I can have the extra round in the same space with the flat magazine bottom. I can have black finish and still have corrosion resistance that equals or exceeds the stainless steel and I get closer to the classic appearance.
Sorry for the long answer, but I really like the new US made Walther Arms pistols and I would have no hesitation recommending either the PPK or the PPK/S.
