I'm partial to the 232....
....and I've owned a Bersa. Nothing wrong with the Bersa, the Sig came in all stainless and I got a good price on it. And that's what I was looking for. The Sig is smoother and more refined. The extra weight of the stainless frame smoothes out the recoil. If Bersa would ever come out with an all stainless model, I would think about it again. As for a PPK, the closest I've owned to one is a FEG SMC-380, a Hungarian clone. Shoots well, actually quite accurate. Nice SA, stiff DA, which is what I heard about PPKs. But OOooohhh, that slide bite! Currently trading it off for a snubbie .357. Friend of mine has the Bersa Thunder CC. Light, fits in a pocket but has enough barrel to "reach out and touch someone" if need be. You might want to check that model out. I also have the CZ83. Excellent shooters, accurate with smooth triggers.
