TruGlo’s Fiber Optic sight set uses traditional fiber optics for bright aiming points, even in low-light conditions. The system utilizes Truglo’s Tri-Dot aiming system by contrasting front and rear colors. It is constructed of CNC-machined steel, concealing the fibers so they cannot be seen by your target, and has TrulGo’s Fortress Finish for a permanent protective coating and maximum protection. Fits Springfield Armory XD Series (XD, XDS, XD-E, XDM, including Mod.2 models, excluding OSP & 5.25 Competition models)
