I recently bought a first generation Colt SAA and found that the single screw at the front of the trigger guard was stripped. Apparently the hole got stripped so someone put some kind of epoxy or filler in the hole then put in a smaller screw. Would like to get the hole repaired and the proper screw replaced. I'm in MN. Can anyone recommend a repair place. Is this the type of repair that most competent gunsmiths could handle? Thanks.
