I have a S&W 610 with a Cylinder & Slide Extreme Duty Rear Sight.
I really like the rear sight. It is beefy and provides a great sight picture. The only problem is that I seem to have to raise the front sight to bisect the fiber optic front sight to get it on target at typical IDPA distances (see pictures below).
The revolver came with the Fiber Optic front sight. I'm not sure of it's height. Can someone tell me what front sight height I should be using?
Also, where should the sight be measured from? "A" or "B"? (see last picture).
