The XS Sights R3D Night Sight Set in green (brand part no. GL-R014P-6G) brings XS’s signature 3-dot tritium sight picture to the Glock 42, 43, 43X, and 48 family of pistols. XS Sights machines the R3D from solid steel bar stock and blacks out the rear notch to boost contrast against the green front dot, so the shooter’s eye locks onto the front sight faster during a defensive draw. The front tritium lamp also charges XS’s proprietary Ember Glow Dot Technology, a photoluminescent ring that absorbs ambient light and keeps glowing brighter than the rear sight at all times, so focus stays downrange instead of splitting attention between front and rear. Among gun sights, this R3D set favors concealed-carry shooters who want a fast, high-contrast sight picture that works in both bright daylight and total darkness.
