Trijicon's Bright & Tough night sights are the standard by which pistol tritium sights get judged, and this set fits Springfield Armory XD, XD(M), and XD-S pistols. Each lamp is a sealed tritium vial housed in an aluminum cylinder and cushioned in silicone rubber, then sealed under a sapphire lens — that construction is why these hold up to years of slide cycling, solvents, and holster wear. The three-dot layout gives a familiar sight picture that transitions naturally from daylight to darkness with no batteries and nothing to switch on. A straightforward, permanent fix for factory sights that vanish in low light.
