The Night Fision GLK004003WGZ Suppressor Height Sights for Glock deliver the brightest tritium night sights on the market with the patented injection molded sleeve design that securely anchors the vials and creates The Perfect Dot, a durable, high-visibility ring that shines brightly both day and night. Built from CNC machined high-quality steel and finished with a black nitride coating for superior wear and corrosion resistance, these sights replace standard Glock sights with a rugged, American-made performance upgrade that stands up to hard use. The design features an added daytime fluorescent or phosphorescent ring for faster target acquisition in varied lighting, ensuring quick alignment under stress. Installation is recommended by gunsmiths, but the sights are engineered to fit Glock suppressor height configurations across multiple models, including 17, 17L, 19, 22, 23, 24, 25, 26, 27, 28, 31, 32, 33, 34, 35, 37, 38, 39, 45, and 48, providing a versatile solution for duty, competition, or recreational shooting. Night Fisions combination of Swiss tritium and American craftsmanship delivers reliable performance when it matters most.
