Your are asking for an opinion. There are several revolvers that would fill this role well- in my personal opinion, the Smith & Wesson Mdl 60 revolver in .357 Magnum would be the revolver of choice. You may also want to look at the Ruger SP101, preferably, in a hammerless configuration if you want it for concealed carry.
