I have a 2x leupold on my redhawk. I like the low power cause it reminds me that I'm limited in range. I also use it with both eyes open and am starting to like it more and more. It did take a little getting used too.
I have a Ruger 454 and use a Millet red dot scope. I've shot a 1.5 inch groups at 50 yards with this setup. I also put double sided tape in the bottom scope rings. this will prevent your scope from shifting from recoil. Jim
