It's been my experience, just from a shooting buddy, that the Ruger's are fine revolvers. Now, that being said they will need a trigger job if you don't like a heavy trigger pull.
I think the Super Redhawk is a double\single action revolver. I own a few S&W 44 mag's. Both are double\single action. Frankly it's pretty rare that I actually shoot then in DA. Target shooting and "plinking" I use SA 99% of the time. I've taken several doe with my 44's and again, always in SA. Never DA.
If your going to shoot it in any type of event where "speed" is essential, then you will want DA. If not, consider saving your dollars and get the less expensive SA Blackhawk.
But, you know what you want. I'm just tossing out some thoughts.
Good luck with your buy......I know from personal experience that shooting the 44's are fun!!
