Trijicon HD XR Night Sight Set for Large-Frame Glock MOS, Yellow Front Outline
Model GL645-C-601169 brings the Trijicon HD XR sight design to the large-frame Glock MOS application, with a yellow front outline and a MOS-fit rear. This is the standard-height configuration, distinct from the taller HD XR suppressor/optic-height set.
A thin, 0.122-inch front post preserves the HD XR profile, while the yellow front ring provides a contrasting reference in daylight. Three green tritium lamps illuminate the front and rear dots without batteries. The rear uses a serrated face and a U-shaped notch with black lamp outlines.
Match the set to the specific large-frame MOS slide before purchase. MOS compatibility describes the sight application; it does not by itself establish that the sights will be visible through a mounted red dot. Where extra clearance is needed, compare the separate suppressor/optic-height version and the dimensions required by the complete setup.
