I'm recommending the Ruger SP series in .357 or the Charter Arms. The Charter Arms though is unshrouded.
Man, that's a hand cannon!!!!
I would second the Ruger Alaskan suggestion. Chambered in .454 Casull it can also be loaded with the milder .45 Long Colt rounds.
Oh man, is there any hope of having functioning wrists after firing that? Not to mention ears?
