With the challenges of law enforcement and military in mind, Trijicon HD Night Sights is a self-luminous three dot sight set which uses 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. The u-notched rear sight is angled and serrated to reduce glare, while the front sight has a tall blade. The protective clear coat resists powder residue and cleaning solvents to keep the color bright for years.
This sight set will fit Glock models: 20/21/21SF/29/30/36/41. It has a green front sight with a yellow outline.
