The Trijicon HD XR Suppressor/Optic Height Sight Set for Glock large frame MOS pistols (brand part no. 601177) combines the HD XR’s fine front post with a raised sight plane for suppressed and optic-equipped pistols. Trijicon fits tall steel housings with green tritium lamps front and rear, a yellow photoluminescent ring around the front lamp for low-light pickup, and a thinner front post that exposes more of the target at distance. The raised height keeps the irons usable over a suppressor body and co-witnesses through a slide-mounted optic. Among gun sights, this set favors large-frame Glock MOS owners running a can or dot who want a fine tritium aiming point.
