That's why the current US made (S&W) PPK has a redesigned frame with a larger tang. Not quite a beaver tail, but enough to make hammer bite or rail cuts a thing of the past. I carried an older model (Interarms Stainless) PPK as my daily CCW piece for nearly ten years in an IWB holster. It carried well but it's not very pleasant to shoot. Although it's quite accurate and reliable, the DA pull is very heavy and the recoil gives a sharp sting to the heel of your palm.If you have large hands, you will find the PPK will leave two bloody tracks in the shooting hand between the thumb and index finger. Definiately not a gun for a beefy American hand.
We're not discussing the "S", that's a different gun from the PPK. The "S" has the full metal backstrap grip frame and holds a slightly larger magazine. I've heard MANY complaints about the "S" over the last 20 years. My dad bought one NIB back in the 80's. We went to the range with a few different boxes of ammo and couldn't get through a full magazine without a problem. He dumped it and got a PPK, which still works perfectly to this day.My opinion: POS. Mine (a PPK/S) locked up after 75 rounds and it took 3 weeks to talk to a person in "customer service". Poor pistol, worse after sale service (S&W now) makes for a bad combination -- especially if you plan to trust your life with it.
