Trijicon Suppressor/Optic Height HD XR Features The Trijicon HD XR Night Sight Set is built as a self-luminous three-dot night sight system that uses a highly visible photoluminescent paint outline around each tritium insert to improve visibility in both bright daylight and total darkness. The front sight s domed sapphire and tritium lens is twice as bright as the standard HD front sight helping shooters acquire the front sight faster during a defensive draw or competitive stage. A thinner front sight post increases the shooter s field of view around the sight making it easier to identify threats track moving targets and confirm hits at longer distances. The rear sight s U notch design is angled and serrated to reduce glare under harsh lighting while keeping the shooter s focus on the front sight. Sized specifically for suppressor and optic height use this set is built to co-witness properly with a slide-mounted red dot on Glock 42 43 43X 43X MOS 48 and 48 MOS pistols or to serve as taller standalone sights when a suppressor is mounted. The green tritium with orange outline front and green tritium with black outline rear combination gives shooters a fast high-contrast reference for quick target transitions. Machined from steel and finished in black the sights are built to withstand the wear of daily carry and repeated holstering. For law enforcement and competitive shooters who need precise engagement capability in any light on a Glock micro-compact platform the Trijicon HD XR set delivers a proven high-visibility upgrade.
