The Trijicon HD XR Suppressor/Optic Height Sights provide precision long-range accuracy and backup visibility for standard-frame Glock MOS pistols, including the G17, G19, G22, G23, G34, and G45 models. Machined from solid steel, this system uses an ultra-thin 0.122-inch front post that expands your side-to-side sight pocket, creating a wide downrange field of view for quick target tracking and cleaner point-of-impact visibility. It operates entirely battery-free via self-luminous green tritium core lamps to guarantee clear target alignment in zero-light scenarios, paired with an aggressive photoluminescent yellow front ring that drives rapid eye focus during high-speed daylight transitions. The serrated rear face filters out distracting environmental glare, while the elevated physical height profile allows the sights to clear attached muzzle suppressors and seamlessly co-witness over slide-mounted miniature reflex optics.
