Product Description The Night Fision GLK001230362YGZG Tritium Night Sight Set is purpose-built for Glock 19 and Glock 45 pistols, providing reliable, self-illuminating target acquisition in any lighting environment. The set features a yellow-outlined tritium front sight for fast, intuitive focus and a blacked-out tritium rear sight that creates a high-contrast sight picture without distracting illumination at the rear. Both sights are marked "NF H3," confirming the use of tritium (hydrogen-3) vials for long-lasting, battery-free glow. Serrated side walls on both the front and rear sight bodies minimize glare and reflection for a cleaner, more precise sight picture. Designed as a direct drop-in replacement, these sights install without permanent modifications to the firearm.
