It really depends on what gun feels best to you. If they both feel great then Its up to if you want D/a or S/a. If you don't mind either then both will shoot great with select handloads well that is my experience with rugers I needed handloads to get there full potential. But if you are worried about which one will handle the heavy loads better for longer and not fly apart then its the ruger super redhawk. Strongest gun around outside the five shooters
