Get a good holster; it is a lot safer.   I carried the PPK/S, an Interarms version, a lot back in my suit and tie days because I'm not a big guy and the PPK/S wouldn't print noticeably with a good shoulder holster, though it was best to have your suit tailored for carrying it.   Any more, I carry something a little heftier, a S-S P 226 9mm, and don't worry much if it prints.

James Bond was right, though, the PPK was THE fashionable pistol, and I might just frame mine and hang it on the wall.   And I'll always have that scar on my thumb joint to remind me that a PPK bites if you aren't very careful of how you hold it.
