XS Sights R3D 3 Dot Set Tritium Square Front and Notch Rear Sight for Glock Small Frame Pistol

XS Sights R3D 3 Dot Set delivers a traditional 3-dot tritium sight picture with notch and post configuration. The blacked-out rear sight enhances contrast against the front sight for improved target acquisition. The front sight comes in orange or green and incorporates Ember(R) Glow Dot Technology, which absorbs ambient light and glows in low-light conditions. The front tritium lamp energizes the Ember dot, ensuring the front sight glows brighter than the rear at all times to maintain downrange focus. R3D sights provide the brightest notch and post option available for fast and accurate shooting in both bright and low-light environments.
