Right now the Uberti seems to have the highest ratings, given a loose and very unofficial poll. The Cattleman in 45LC/4.75" bbl (SKU 344100) is what I'm looking at most, but I still don't know enough yet.
I never really fancied the open tops; always made me wonder how they would hold up given hundreds of rounds. If it was purely CFDA then no issue, but if I use this for other stuff it will need to be solid. From the looks of it the cartridge changes came in 1871, only a couple years before the Peacemaker.
