The XS Sights R3D Night Sights (part no. SI-R015P-6G) cover a wide range of SIG SAUER models, including the P320, P365, P225, P226, and P229, as well as the Springfield Armory XD. Every R3D set is CNC machined from solid steel bar stock in XS’s Fort Worth, Texas shop, and the green front insert uses Glow Dot photoluminescent technology so it charges from ambient light and glows brighter than the rear sight.

Frequently Asked Questions

Does this fit my Sig P320/P365/P225/P226/P229 or Springfield XD? Yes, this R3D set is sized specifically for Sig P320/P365/P225/P226/P229 or Springfield XD; always confirm your exact model and generation against the fitment list before ordering.

Do these sights need batteries? No. The tritium front is self-illuminating, and the Glow Dot front insert charges passively from ambient light and the tritium lamp itself.

Why is the front sight green? The green insert gives the sharpest daylight contrast against the target; XS also offers other front colors on the same R3D platform for shooters who prefer a different look.
