Thanks for the responses! An Accusport Bisley is on my "list" either a 44 or 45. How difficult is converting a standard BH, or in this case a BH Hunter? I don't own any single actions, so I was wondering if this could be a do-it-yourself project or if I'd need a gunsmith to do it. Also, what's a good source for the Bisley frame, trigger, and hammer? Thanks again!
