Trijicon HD Tritium Night Sight Set Features The Trijicon HD Night Sight Set uses self-luminous three-dot tritium construction so the shooter always has a reference point whether in daylight or total darkness. The front sight combines a green tritium vial under a domed sapphire lens with a bold orange photoluminescent outline which pulls the eye to the front sight first and speeds target acquisition under stress. The rear sight is a green tritium insert with a black outline set into a serrated angled U notch that cuts glare and keeps the shooter s focus locked on the front sight rather than the rear. Together the two sights form a fast intuitive sighting system built for the demands of personal protection and duty carry. Both sights are machined from steel and finished in black for corrosion resistance and long service life on a daily carry pistol. The set is purpose built to fit the Smith and Wesson M&P C.O.R.E. and M&P M2.0 Optics Ready pistols dropping in without modification to the slide. At just 0.42 oz combined the sights add negligible weight while delivering a meaningful upgrade over factory sights in low light performance. For shooters who carry an M&P C.O.R.E. or M2.0 for personal defense or duty this Trijicon HD set is for sale at GrabAGun as a proven tested upgrade.
