Trijicon self-luminous iron sights are proven to give shooters five times greater night fire accuracy-with the same speed as instinctive shooting. Trijicon is proud of its reputation for incredibly reliable night sights. The unique shock resistant design is patented and used exclusively by Trijicon. That's why Trijicon Bright & Tough night sights are the first choice of major handgun manufacturers, and standard issue with hundreds of municipal and county departments, numerous state police departments and several Federal agencies.
Their metal body is precision machined and custom manufactured for specific handgun makes and models. Glass lamps filled with pressurized tritium gas, glow bright green at night. Warranted for 12 years. Professional gunsmithing by a Trijicon-approved gunsmith is required to obtain the 12-year warranty against lamp failure. Polished sapphire windows, aluminum cylinders, silicone rubber cushions the glass lamp within the aluminum housing for excellent shock protection, and the larger front dot provides extra distinction and brightness.
