I just made the switch to open in 3 gun competition and have mastered moving letting the dot come to the target with my shotgun. I am doing drills with my pistol and practicing with the dot off seems to help. I had a battery go out on my pistol during a stage a few weeks ago and was still hitting steel at 15 yds looking thru the glass. I don't recommend this but I realized then that I could move the gun not the dot.
