Trijicon HD NS Glock 42 HD Night Sight

Designed with the challenges of law enforcement and the military, Trijicon night sights are a great addition to any defensive handgun. These sights use tritium-phosphor lamps to glow brightly at night. The front sight is highlighted by a photo luminescent yellow circle, and the front surface of the rear sight is steeply hooked to assist in emergency one-handed slide operation.
