I carried my Interarms stainless PPK/S all the way to the gunshop and traded it in on a nice S&W Model 15-3 with a 2" barrel. I know it won't bite my hand or jam on JHP ammo.
I have a Sig P232 (the Sig version of the PPK/S. I carry it in a DeSantis Sof-Tuk IWB. Very comfortable carry. I have never had it Fail-to -Chamber any type of round. I did polish the feed ramp.
