If you fancy doing it yourself you might consider the Brownell's barrel hone: http://www.brownells.com/aspx/NS/store/P...NG+FLEX+HONE%7e

I think it can be bought else where for less money. If this is the only gun I would consider having it done by a pro. Mike Orlen of this Board id highly recommended. Mike's contact info: orlen@verizon.net 413-256-1630
