The Night Fision Costa Ludus Night Sight Set for Glock, Yellow Front (brand part no. GLK-001-010-YGXG) pairs a proprietary Night Fision Perfect Dot in the front sight with a horizontal tritium bar in the rear, creating a sight picture unlike a standard 3-dot setup. The serrated, low-glare rear stays clear of a mounted red dot for a minimal co-witness, and Night Fision’s patented injection-molded sleeve holds the tritium vials securely using ballistic materials. These sights carry more tritium than most competitors and use a domed lens for a sharp, defined glow.
