I like a bright front sight and a black rear. All those dots are too busy. Right now my favorite fronts are Aeroteks on my Glocks, red fiber and Green tritium, always a dot to look at. I black the rear stock sights out with a sharpie. On std sights I've been known to attack the front sight with orange nail polish. I want to see that thing, and just be vaguely aware of the rear.
I want to get a horz. tritium bar rear for one of my Glocks, I think Heinie makes what I want, if not I'll just go straight 8, one dot rear, one in front. Align vertically.
