The Night Fision GLK001007YGZ Tritium Night Sights for Glock deliver a precise, confident shooting experience with green tritium glow and a yellow outline on the front sight paired with a green tritium black outline rear sight, designed to fit Glock 17/17L/19/22 and a wide range of models. Night Fisions patented injection molded sleeve securely holds a higher volume of Swiss tritium, while a domed lens collimates the rays to produce a crisper, more defined glow in low light. These sights are CNC machined from high-quality steel and finished with a Black Nitride coating to enhance wear resistance and corrosion protection, ensuring durability under demanding conditions. Built in the USA with precision engineering, they offer reliability for duty, self-defense, and night-time precision practice, and are ideal for shooters who demand maximum visibility in dim environments. The combination of bright, legible reticles and a robust construction helps improve target acquisition and accuracy when every shot counts, making Night Fision the preferred choice for Glock owners seeking long-lasting, high-contrast night sights that perform under stress.
