The Trijicon HD XR Suppressor/Optic Height Sights represent an elite tactical blending of precision aiming and elevated clearance for Glock slimline slides, including the G42, G43, G43X, G43X MOS, G48, and G48 MOS. Forged from robust steel, this self-luminous iron sight set features a signature ultra-thin 0.122-inch front sight post that significantly expands your field of view for faster target identification and cleaner tracking at extended distances. The front blade houses an aggressive photoluminescent yellow outline that pulls your focus instantly to the green tritium core, while the steep, serrated "U" notch rear face cuts down on daytime glare and isolates your sight alignment. Engineered with an increased physical height profile, this configuration smoothly co-witnesses over slide-mounted miniature optics (like the Trijicon RMRcc) and completely clears the top edge of attached muzzle suppressors.
