Have an Interarms stainless PPK. It has fed all types of hollowpoints tried, and shot them all accurately. It does have sharp edges on the trigger guard and front strap of grip, and the hammer will bight those with large meaty hands. It requires a tight grip for proper function, tough to do if your hands are larger sized. Judging by the number of negative opinions on various boards, there is just as likely to be some lemons out there.
Once let a friend try it, and it jammed on him each time. By coincedense he has very large hands and not accustomed to shooting small blow back semi-autos.
Was just out trying shooting it this evening, in the process of testing out new batch of Win White box 380's. The new ones appear to be coming with a flat front bullet, kinda a cross between a rnfp bullet and truncated cone style, with a decent little meplat on em. Again the Walther had 100 % reliabilty.
