Go with a Ruger. I can tell you from experience as an occasional guide in Mt. you are not going to find a tougher gun. I have a S&W .44 mountain gun which has a good action and with the right load a good defensive gun. A 8 3/8 nickel plated, pinned & recessed S&W .44mag. Had 2 Ruger redhawk's 7 1/2. Had A Ruger Super redhawk 9 1/2. Had 2 7 1/2 Vaquero's .44mag & 2 5 1/2 Vaguero's in 44mag. I still have a 7 1/2 Ruger super Blackhawk Hunter in
.44 mag. One thing I have learned is that adjustable sights when dropped
break. One other thing I can tell you, when hunting dangerous game or in
country where dangerous game exists a single action is a better choice. Let
me explain. Garry Hansen is a full time government hunter for the Dept. of
Agriculture in Colorado. One time when chasing a lion getting a shot here and
there, he just ejected the spent rounds and replaced them as needed when
still moving, keeping the gun loaded at all times. Had that been a double
action he would have a problems without stopping. Also, with the cylinder
open, the gun is rendered temporarly inoporative with the risk of dumping the
good rounds on the ground.
I mention that story because even though I have had encounters with grizzly and mountain lion I have never had to drop the hammer. All I go in the
woods now with are Ruger Vaquero's in .45Colt with 300 grain Hardcasts and
25grains of H110. My hunting gun is 7 1/2. When guiding or carrying secondary it's a 5 1/2 Bisley Vaquero. When hiking it's a Birdshead Vaquero.
As much as I love my .44's, one thing I have learned is that the .45Colt
equals the .44mag in performance with less noise & recoil.
