Ok so I have been seriously thinking about converting one of my old Kimbers to this round for black bear. The Kimber has an external extractor. Would that be a problem? I have never had any problems with the extractor but this is a way higher pressure round. Does the kit com with an extractor? Its to late in the day to call Clark Custom and they apparently frown on emails. So does anyone have a clue about external extractors in 1911's with 460?
