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 model is compatible with Sig P225/P226/P228/P239/P320 and has a yellow front sight outline.
