XS Sights R3D 2.0 Green Night Sight for Glock 19 Pistol

XS Sights brings you the R3D 2.0 Green Night Sight, a second-generation night sight system engineered to deliver increased brightness and strength. Installation is streamlined—these sights require 50% less force to mount compared to earlier designs. Built to handle years of everyday carry and hard use, the R3D 2.0 features a serrated blacked-out rear sight paired with a dual-illuminated tritium photoluminescent front sight that keeps your focus downrange. The notch and post configuration delivers the brightest option available, enabling fast and accurate shooting whether conditions are bright or dark.
