The XS Sights R3D Night Sights is a handgun night sight set designed for three-dot sight alignment on large frame Glock pistols.

This XS Sights R3D Night Sights model features a green tritium front dot with a black rear sight to maintain visual separation between sight elements. The sight system uses a traditional notch and post configuration with tritium illumination in both components. This model fits Glock 20, 21, 29, 30, 30S, 37, and 41 platforms. The steel construction includes a blued finish for wear resistance and consistent fit. In standard configurations, the front sight incorporates a glow dot element that absorbs ambient light to remain visible in low-light conditions. This product is used for maintaining a consistent three-dot sight picture in both daylight and reduced lighting environments.
