Night sights transform your handgun into a low-light weapon system, and the XS Sights R3D Night Sights for Sig Sauer and Springfield Armory deliver proven performance in conditions where standard iron sights fail. These tritium-powered sights combine a traditional 3-dot sight picture with XS's proprietary Ember Glow Dot Technology—an ambient-light-absorbing feature that amplifies visibility without batteries or electronics. Whether you're training after dark, responding to a home-defense scenario, or shooting competitions under varied lighting, the R3D system keeps your front sight dominant and your hits on target.
The R3D design prioritizes contrast and speed. A blacked-out rear sight frame isolates your front sight in low light, while the brighter front tritium lamp ensures you won't confuse it with the dimmer rear vials when visibility drops. The front blade measures 0.145 inches wide and the rear notch 0.170 inches, giving you better sight definition than many factory options. Choose green tritium if low-light performance is your priority—it delivers the brightest glow intensity in darkness. If you shoot in brighter conditions and need maximum contrast, the orange front ring option maintains low-light visibility while standing out more sharply in daylight. Both configurations are installed on this model with green tritium.
Installation is straightforward: use a sight pusher tool, or if you prefer a budget approach, a hammer and punch will do the job. No gunsmithing required. These sights are built for shooters who refuse to compromise on sight picture clarity, whether they're checking zero at the range or depending on their pistol when it matters most.

Green tritium offers the brightest glow intensity in low-light and no-light situations, making it the preferred choice for home defense and night shooting. Orange provides superior contrast in bright daylight while still maintaining visibility in low light. This model comes with green tritium front and rear.
No. A sight pusher tool makes installation quick and precise. If you don't have a pusher, a hammer and punch will work—XS designed these sights for easy user installation.
The Ember Glow Dot absorbs ambient light from your shooting environment and glows brighter in low-light conditions. This passive technology requires no batteries or electronics and enhances the brightness of the tritium vials when you need it most.
