I have just recieved a Colt Python 357 mag with a 2 1/2 inch barrel. I has only been shot maybe ten times and has been sitting for probably 6 years. It has alittle pitting along the top of the rail and the screw from the rear adjustable sites is gone. NOW..after all that..If I use a dremmel and polish the pit marks smooth can I replace the bluing myself or should I just say phooey and send it to someone else to do it...If so, Who does a good job? Thanks
