The Night Fision GLK001003OGZ Tritium Night Sights For Glock deliver a brighter, more durable aiming solution with their patented injection molded sleeve design that securely holds Swiss tritium vials and creates The Perfect Dot ring for maximum visibility day and night, a feature that enhances target acquisition in dynamic lighting while reducing sight picture noise. These Glow Dome front sights pair a green tritium insert with an orange outline for fast front sight focus, while the rear sight uses a green tritium with a black outline to maintain a clean, snag-free profile. CNC machined from high-quality steel and finished with a corrosion-resistant black nitride coating, they stand up to everyday carry and the rigors of use in demanding environments. Installation is recommended by gunsmiths to ensure precise alignment, and the result is a robust sighting system built in the USA with Swiss tritium for long-lasting brightness. Specifically designed to fit Glock 17, 17L, 19, and 22 models, these sights improve site picture comprehension under varied lighting, enabling quicker target acquisition, improved accuracy, and enhanced confidence whether at the range, in duty scenarios, or during night-time practice.
