I prefer the Ruger BH .45, or the Ruger SBH .44 because of their power to weight ratio.
If you are one of those who feels safer with a double action for bear protection...by all means, the S&W MG is the way to go, again, weighs less than other .44 Mag double actions.
My personal bumming gun / deer gun is a Ruger Vaquero that I shortened the bbl to 4.5", cut and mounted a dovetailed front sight into the bbl, modified the rear sight channel in the frame, set the bbl back a thread, cut a Taylor thoat in it, polished the warning label off the bbl, installed a SBH trigger and hammer, a SB Dragon (the longer one with the square backed trigger guard) gripframe round butted gripframs and stocks, and did a quicky trigger job to.
Now having said all that - one could go buy a BH, or SBH in 4 5/8" and have just as functional a gun, and all the time I spent slicking mine up might be better spent shooting it. - Josh M.
