I have a SBH with a misaligned grip frame, sticks out about .005 on left side, recessed same amount on right side. Lines up perfectly with screws removed, ends up misaligned the same with screws in place. On close examination, holes in gf are off center. Has anyone tried reducing the diameter of the screw heads to compensate for this? I realize it would take .010 reduction in head diameter to make this work and that's quite abit. Thanks
