Trust this optic with my life - Trijicon Heavy Duty Night Sights Yellow Front Outline Fits Glock 42 GL113-C-600784

I use this HD night sight on my CCW firearm. Its incredibly vibrant in all conditions and is very low profile. The only down side of this optic is transitional shooting from a dark area to a very light area where the fiber optic does not outshine or washout the tritium. Other than that the sharp angle and backing of the rear sight are great for one handed operation of your firearm!
