Built with the dynamic handgun shooter in mind, the Trijicon HD is a three dot green tritium night sight set where the front sight has a photoluminescent paint outline that draws your focus to it. The HD XR features a thinner front sight compared to the standard HD set, which allows a much larger field of view and assists with acquiring smaller targets or targets at distance. The rear sight is also designed with a steep hook for one hand slide manipulations off a belt or holster. The tritium lamps are also warranted by Trijicon for 12 years from date of manufacture,
