The AmeriGlo Classic Tritium Rear Sight (brand part number XD191R) brings a self-luminous night sight to the Springfield XD, XD-M, and XD-S pistols. AmeriGlo machines the sight from steel and fits it with Swiss-made tritium light sources, the same three-dot layout that’s become the standard for personal defense, military, and law enforcement pistols. This rear sight carries two green tritium lamps with a white outline, matching the standard AmeriGlo Classic three-dot front-and-rear pairing for a fast, low-light sight picture. It’s built specifically for XD-family pistols and is not compatible with the OSP optics-cut models.
