I bought one for my wife and she hated it, mainly because the slide was too tough for her to manipulate for her.
I carried it as a on duty BUG and often carried it when out running, biking, or in the kayak. Mine was reliable, mainly using Federal Hydra-Shok and was very accurate. Only downside was, in .380 ACP, the PPKS is not a fun gun to shoot a lot. I'm not recoil sensitive, but I didn't like shooting it more than one or two magazines without putting on shooting gloves. The blowback operation combined with the .380 round can be pretty snappy on your hand.
