Got a question for all you EXPERTS. Looking at picking up a used Ed Brown. It does not apprear to have been messed with, it's a BROWN stammped barrel. Anyway, here's the deal. The barrel is "riding the link". The barrels lower legs do not contact the slide stop pin. Will Brown warrany repair this since I'm not the origional owner? Would it be better to have the legs built up, or have a new barrel installed/fitted?
