I chose the PPK.

While I do own a couple of J-frame .38s, these are the guns a carry the least. I've always had problems with the grip on these. Its just too small for my hands and I don't shoot them very well. Yeah, I can easily change the grips. But by the time I get a set of grips on the gun that give me proper control and allow me to shoot it well, I've lost all the advantage of its small size. I might as well be carrying a K-frame, which is what I actually do.
I very rarely pocket carry. Maybe a jacket pocket during cold weather once in a while, but absolutely never in my pants pocket. That might work fine for you folks wearing dress slacks or cargo shorts, but I normally wear jeans. For me pocket carry is uncomfortable, slow and awkward as Hell. Not to mention impossible from a seated position.

OTOH, the PPK is slim, flat fits my hand well, shoots great and carries like a dream.
I don't know where all these malfunctioning PPKs are coming from, but mine have been completely reliable.
For me, there's not even a choice to be made here.
