What is a good brand/model of night sights that will work well during the day? I've heard a lot about how amazing Trijicon night sights are but also seen a lot of criticism that they are almost impossible to use at the range. Also, just because it randomly occurred to me, what the heck is the difference between novak sights and regular sights? Is it just look? Edit...thought of another question...is there a distinct advantage or disadvantage to fiber optic?
