Trijicon sights for 4006tsw - Trijicon Bright & Tough SA15 Night Sights for Smith&Wesson .40 w/ Long Rear (Novak LoMount)

Sights are bright and an improvement over the factory sights. The outer ring is great for picking up in the daylight and the tritium at night is fairly good to pickup. The dots are pretty small to pick up but that my just be my older eyes. I recommend getting green front and yellow rear. Works to distinguish front from back quickly and yellow picks up almost as easily as green. I used a gunsmith to install them.
