DXT2 Night Sights are defensive tritium sights designed to enhance your EDC pistol. The front sight uses a proprietary photoluminescent Glow Dot that absorbs ambient light and glows in low light. The convex dot’s additional surface area increases light absorption, intensifying the charge of the Glow Dot. The shallow V rear has a simple, low profile that provides a wide field of view.
