Just got my contender back from the factory where they replaced the guts of the frame. For nothing but me shipping it to them! That is great service! Anyway they sent me a diagram/letter stating that some pachmayr grips do not have enough/proper clearance for the hammer spring and that can cause it to weaken. They said that modifications could be done (on the grip) but that they would not do it and that I could be disqualified from competitions. My only competition is getting close enough to pop that big ol' buck, so I am not worried about that. Is anybody familiar with this and just what do I need to do?
