Hi all, a while back, I was corresponding with an idividual from this site, about a blackhawk, flattop, .357, 10" 8 groove. I know they are very rare, and expensive. How about a 4-5/8", flattop, .357, 8 groove? Are they pretty rare and expensive as well, or is it just another standard flattop??????? Any info, would be greatly appreciated. Thank you.
