I had the same issue with an Interarms PPK that I bought new ~10yrs ago. It went back to the factory and was fixed. Take it to a dealer and see if they can still send it back. It was not an uncommon problem. Call Walther USA, or S&W, or whoever owns them now and ask about it. Maybe they can just send the shop the correct parts. Actually, you might be better off calling Earl's Walther Repair and asking them about it first. Nobody knows Walther stuff better than Earls.
