This is just up my ally, I have several different types of red dot sights. I have the Tasco Pro-point PD3 on my Redhawk 44 MAG, Ruger .22 slab side and Ruger P4 .22, a Bushnell Holo sight on my S&W 625 in 45 ACP, Aim point on my H&K USC 45 ACP, a Millet on a Ruger Super Redhawk 44 MAG and an Ultra Dot on my S&W500MAG. Surprising is the Tasco Pro Points have held up to thousands of round, the Bushnell has done a great job on the S&W625 after thousands of rounds. The ultra dot is holding up very well also. I did have to send the Aim Point back for repair due to a faulty switch, the turn around was just over a week which I think was great service from Aim Point. I also had to send back the Millet due to the dot going off and on after each shot. But again Millet sent me a new one in about 2 weeks. But if I had to just pick one it would be the Bushnell Holo sight. Then Aim Point. :grin:
