It is hard to conceal a single action Ruger. I have no problem sticking my Ruger Blackhawk with a 6.5" barrel in my pants. It is not an EDC but if the threat is elevated either my Blackhawk or Super Blackhawk is the gun I want in my hand. They will go bang no matter what!
Colt (see website) makes their classic gun in .357 -- probably hard to get -- they always seem to be back-ordered. Uberti in Italy makes quality Colt replicas with the Colt-like "4-click" hammer-- imported by Taylors (in Virginia --see website), among many others. Leaving aside the history, etc., many people would say Ruger's Blackhawk is the weapon of choice for heavy duty work, with the Vaquero equally well regarded in a lighter, more traditional gun.
