The bushing to my Series 70 Colt 1911 recently broke... God knows how many rounds I've put through that gun. Anyhow, I need to get the bushing replaced, but I don't know where to buy a replacement. I know I could just pick up a copy of shotgun news and take my pick of dealers, but I'd rather go through a recommendation from one of you good people. Any and all help will be appreciated.
