Trijicon HD XR Suppressor/Optic Height Night Sight Set for Large-Frame Glock MOS, Yellow Front Outline
The GL345-C-601177 set is the yellow-outline Trijicon HD XR suppressor/optic-height option for the large-frame Glock MOS application. It combines an elevated front-and-rear sight pair with the HD XR family’s narrow front post, rather than the standard-height GL645 profile.
The yellow photoluminescent front ring provides daytime contrast against the rear sight, which uses black lamp outlines. Three green tritium lamps supply battery-free illumination. The front post is 0.122 inch wide, and the serrated rear face surrounds a U-shaped notch.
The taller profile is intended for applications requiring additional sight clearance, but it does not establish a universal co-witness height. Confirm the exact large-frame MOS slide and the optic, mounting plate, or suppressor dimensions. This set should not be confused with the slim-frame Glock 43X/48 MOS version, despite their shared height category.
