Somehow, the black on my new S&W 1911 has been messed up. There is a Circle off to the side of the hole for the slide lock. It looks like either the finish is gone or lightened up. There is no way it is just wear from the slide stop, as it extends about 1/16away from the hole. I have tried to use a Birchwood-Casey gun Blue pen to no avail to repair a scratch in the area, and fear that may have ruined the surrounding area. Has anybody used the Birchwood casey SUper Black touch up pens. I am afraid that maybe my use of the blueing pen may have made it worse, so don't really want to send it to S&W. Any experience with the Super Black pen?
