XS Sights R3D 3-Dot Green Tritium Night Sights for Sig P226/P320 & Springfield XD/XD-S/XDM

The XS Sights R3D Night Sights are a self-illuminating tritium sight set built around a traditional 3-dot notch-and-post sight picture for fast front-sight acquisition in low light and high-stress conditions. The rear is blacked out to maximize contrast against the front, while the rear tritium lamps stay visible for low-light indexing.

Both the front and rear sights use green tritium lamps set into a CNC-machined steel housing finished in a low-glare black coating that blends with most factory slides. The front sight carries a green outline ring around the tritium lamp, drawing the shooter's eye to the post for quicker alignment than a plain dot. Tritium is self-powered, so the sights glow continuously with no batteries or ambient light required.

This SIR015P6G variant is a press-fit configuration made for Sig Sauer P226 and P320 pistols along with the Springfield XD, XD-S, and XDM series. R3D sights are designed as a press-fit installation for these slides and work with a standard sight pusher.

Whether for daily-carry, home-defense, or duty use, the R3D delivers a clean tritium 3-dot picture that helps you find the front sight faster when it matters most.
