Trijicon HD XR Night Sight Set for Smith & Wesson M&P C.O.R.E./M2.0 Optics Ready, Yellow Front Outline
Model SA640-C-601173 is the yellow-outline Trijicon HD XR set for Smith & Wesson M&P C.O.R.E. and M&P M2.0 Optics Ready pistols. Its platform-specific front-and-rear pair is separate from the HD XR set for conventional M&P and SD VE slides.
A 0.122-inch front post supplies the narrow HD XR profile. The yellow photoluminescent outline contrasts with the black rear outlines, while green tritium lamps illuminate all three dots without battery power. The serrated U-notch rear provides a subdued background for the colored front.
An optics-ready pistol application is not the same thing as a suppressor-height sight. This is the standard-height SA640 configuration, so visibility through an installed optic depends on the complete slide, optic, and mounting arrangement. Check the separate suppressor/optic-height application when extra clearance is required.
