TRIJICON SUP NS GRN FOR GLK 9MM YELL: Trijicon Bright & Tough(TM) Night Sights are three-dot iron sights that increase night-fire shooting accuracy by as much as five times over conventional sights. Equally impressive, they do so with the same speed as instinctive shooting – and without the need for batteries.
