I read someplace that the .44-40 was used more than any other to put men six feet under in the Old West. Good caliber to own. I always wanted Colt .45 six shot military revolver. It was the most powerful handgun used by US Military 255gr at about 950fps if I recall correctly. Never seem to find good clean one and the few I have examined had issues preventing me from buying them. Old vintage revolvers are nice to own because they haven't improved over the years except in more advanced manufacturing procedures making them cheaper to make. What you read in gun magazines as improved in reality means cheaper to make.
