XS Sights R3D 2.0 Night Sight Set Green Tritium Front, Black Oxide Frame - S&W M&P 2.0 OR Full Size & Compact

The XS Sights R3D 2.0 Night Sight Set delivers a brighter, more durable, and easier-to-install tritium sighting system purpose-built for Smith & Wesson M&P 2.0 optic-ready (OR) pistols in both full size and compact configurations. Designed as a direct-fit upgrade, the R3D 2.0 preserves the classic 3-dot notch-and-post sight picture while incorporating modern defensive features that make low-light and stress-fire shooting faster and more intuitive.

The set pairs a green tritium-illuminated front post with a blacked-out rear notch that increases contrast against the front element, helping the eye lock onto the front sight quickly. The 2.0 generation is engineered to be roughly 50% brighter than the original R3D rear sights, and the dual-illuminated front sight combines a tritium insert with a photoluminescent outline that picks up ambient light during the day. Installation uses XS's EasyPress system, eliminating the need for filing or hammering during fitment.

Built around a steel housing finished in a low-glare Black Oxide coating, the sights sit low enough to clear common optic-ready slide cuts without interference, making them a practical backup iron sight solution for M&P 2.0 owners who run a red dot as their primary aiming system. Whether you run the slide bare or co-witness under an RDS, the R3D 2.0 set gives you a reliable aiming reference that performs in daylight, low light, and total darkness.
