XS Sights R3D Night Sights for Smith & Wesson - Black | Green Tritium Orange Front & Green Tritium Rear

The XS Sights R3D Night Sights for Smith & Wesson bring genuine low-light capability to your handgun without the guesswork. Built around a classic three-dot sight picture, these tritium night sights blend traditional geometry with modern luminous technology—giving you a fast, intuitive aiming solution whether you're shooting in daylight or complete darkness. The blackened rear sight creates contrast against the glowing front post, keeping your focus downrange where it belongs.

What sets the R3D apart is the Ember Glow Dot Technology on the front sight. This dual-source approach means your front post both absorbs ambient light and benefits from tritium charging, making it glow noticeably brighter than the rear at all times. In bright conditions, the Ember dot works passively. In low light or darkness, tritium takes over. The result is genuinely usable sight picture from the range to home defense, without the eye strain of hunting between dim rear dots.

XS Sights backs these with a 10-year no-questions-asked warranty, a straightforward commitment to reliability. The R3D sights fit standard Smith & Wesson holsters, so no gear changes needed—just swap your irons and run.
