Night Fision's Costa Ludus night sights bring competition-proven low-light performance to your Glock duty or carry gun. Engineered for shooters who need reliable target acquisition in darkness or poor lighting, these tritium night sights pair a glowing front post with a rear bar sight, letting you build a sight picture fast when ambient light fades. The orange ring front sight gives you a daylight aiming reference while the green tritium fills the notch for low-light work—a practical two-tool design that handles everything from dawn range sessions to emergency use.
Built for Glock 17, 17L, 17MOS, and 19 platforms, the Costa Ludus sights are a direct retrofit—no gunsmithing required. Night Fision's tritium vials are factory-sealed and comply with DoT regulations, so you know they'll perform reliably for years of service. The black steel construction resists corrosion and holds up to hard use in training and field environments.
Whether you're a competitive shooter refining your low-light skills, a law enforcement professional, or a civilian prepping for home defense, these sights remove the guesswork of finding your front sight when the lights go down. The Trinidad-green rear and orange-ringed front create strong contrast, making transitions between daylight and darkness intuitive.
