I have bought, played with, and sold a Ultradot, 2x, and a 4x for a Redhawk. In the end I didn't shoot any of them any better than my Bisley 45 with irons. I think it was my relationship with the gun and not the optics. Good news is buying used off ebay lets you try it out then sell the one you don't want for nearly the same price if you don't like it.
