I had a PPKS .380, if you like a gun that tries spinning in your hand when you fire it, keep looking for one. The recoil was tough on the webbing between my thumb and forefinger. I happily sold it.
For a small .380, my favorite was a little Llama in the mini 1911 style. That gun shot pop cans at 35 yards and farther.
**Looking back at this, I see you are asking about PPK (s) not PPKS (James Bond style), oh well, I tried.
