Night Fision GLK000001YGX Perfect Dot Tritium Front Sight for Glock 17/17L/19/22 - Green Tritium / Yellow Outline

The Night Fision GLK000001YGX is a Perfect Dot replacement tritium front sight engineered specifically for Glock pistols. Built around a CNC-machined steel body finished in a durable Black Nitride coating, this front sight delivers excellent wear and corrosion resistance for everyday carry and duty-grade use.

Featuring green tritium vials encircled by a high-visibility yellow outline, this front sight uses a domed lens that collimates the tritium glow into a sharp, defined sight picture. Night Fision sights carry more tritium than the average night sight on the market, producing a crisp, well-defined glow for faster, more intuitive sight acquisition in low-light and no-light conditions. Designed to drop into the factory dovetail on Glock 17, 17L, 19, and 22 pistols, this is a clean upgrade path for shooters who already run a Night Fision rear sight or any standard Glock rear blade.

Built in the USA with Swiss-made tritium and a patented injection-molded sleeve that securely retains the tritium vials, this Night Fision front sight is engineered to withstand hard use without chipping, cracking, fading, or peeling. Gunsmith installation is recommended to ensure correct fit, dovetail seating, and sight retention.
