They are such stout guns. They are not too much larger physically than the Smith N Frames. Even though people really mistakenly believe that S&Ws are somehow fragile or weak and limited to milder handloads than they really are, the Ruger Redhawk is a platform that can take some extremely heavy loads. The cylinder on it is longer than even the Blackhawk, and as such, it allows it to chamber handloads that will not chamber in the single action Ruger.
In my early years I experimented with some .44 and .45 loads that really were brutal. Too much influence by Ross Seyfried I suppose.
The 7.5" Redhawk with a dot on it is a real tack driver for launching big slugs through stuff.
