Many years ago I acquired a M45, .22 M&P. The gun is in real nice shape with the exception of the fact that someone stippled the back strap. I'd like to restore the back strap and have a local firearms artisan who is capable. I know that this will mean at least partial rebluing. I'd like to solicit opinions as to whether I leave it alone or restore it. Suggestions on how best to restore it would be welcome as well.
