XS Sights R3D 2.0 Night Sight Set for Sig/Springfield/FN 509 - Green Tritium Front / Black Oxide Frame

The XS Sights R3D 2.0 night sight set delivers a bright, traditional 3-dot tritium sight picture for defensive and duty carry handguns. The second-generation R3D 2.0 design pairs a green tritium front sight with a blacked-out rear blade that boosts front-sight contrast, helping your eye find the front dot faster in low light and at speed.

Built on a steel frame finished in low-glare black oxide, the front and rear blades are dovetail-mounted for a secure, low-profile install. Engineered specifically for the Sig/Springfield/FN 509 pistol platform, the R3D 2.0 is purpose-built for shooters who want dependable night-sight carry without stepping into a red dot.

This is a complete front and rear night sight set ready to drop into your slide. Tritium inserts provide self-illuminated aiming 24/7 with no batteries or switches to manage, making these sights a rugged, maintenance-free upgrade for EDC, home defense, and duty use.
