The Trijicon HD XR Night Sight Set for Smith & Wesson M&P CORE pistols (brand part no. 601173) refines the proven HD platform with a thinner front post that exposes more of the target at distance. Trijicon pairs green tritium lamps front and rear for a battery-free three-dot picture with a yellow photoluminescent ring around the front lamp for fast pickup in fading light. The wide U-notch rear keeps the narrow front post quick to find under stress, and steel housings handle duty and holster wear. Among gun sights, this HD XR set favors M&P CORE shooters who prefer the yellow ring for their lighting conditions.

Frequently Asked Questions

Should I pick yellow or orange? Both rings are photoluminescent; yellow tends to stand out in dimmer indoor light, while orange contrasts strongly outdoors — it comes down to where you shoot most.

Do these sights need batteries? No, the tritium lamps glow continuously without batteries or charging.
