That is a very nicely done explanation. I wish I'd had that the first time I ripped everything apart. One thing that I do a bit differently - Bob Rodgers wrote an article a while back about stripping and cleaning your 1911. He recommends NOT having it in battery when turning the barrel bushing - but having something that won't mar the finish in the ejection port so that the slide is back a bit. This'll keep a nice tight custom fit barrel nice and tight.
