New to the forum and have a question. I am into USGI Garands ,Carbines etc. but reciently picked up a 1967 Non Import Walther PPK 9MM Kunz from a friend. The finish is pretty worn the grips and mag are missing but bore is very good. Which would be correct for this pistol, the brown or blck grips? I want to buy originals for it any good places besides E-bay? Also how many rds does it hold? Also, if I would decide to refinish it would it hurt the value or should I just leave it as is? Thanks Guys
