Night Fision’s Costa Ludus sights deliver a proprietary Perfect Dot® front sight paired with a horizontal tritium bar rear sight, creating a distinctive and unambiguous sight picture. The serrated design minimizes glare, while the shorter rear sight height maintains a minimal co-witness and stays clear of your dot. A patented injection molded sleeve secures the tritium vials using ballistic materials.
Night Fision night sights contain more tritium than typical market competitors, combined with a domed lens engineered to produce a crisp, defined glow. The sights are CNC machined from high quality steel and finished with Black Nitride coating for enhanced wear and corrosion resistance. Built in the USA with Swiss Tritium, these are among the brightest tritium night sights available. The domed lens collimates tritium rays for a sharper sight picture. Gunsmith installation is recommended. Designed to fit Glock Models 42, 43, and 43X.
