Trijicon 600210 Night Sights Glock 17, 19-23 3 Dot Green w/White Black

Trijicon's Bright & Tough Night Sights feature a white ring around the glowing dots for daytime visibility, and for illumination in no light or low light conditions, a tritium-phosphor lamp protected within an aluminum sleeve and capped with a sapphire jewel to evenly distribute light and protect from solvents and puncture. They have a metal body with a silicone rubber cushion for shock protection to the tritium-filled glass lamps.
