The Trijicon HD Night Sights (brand part number 600784) are a green tritium front-and-rear sight set built for the small-frame Glock 42 and 43 pistols. Trijicon built the HD line for tactical shooters, pairing a taller front blade ringed in photoluminescent paint with a rear sight outlined in black and cut with a wider U-shaped notch, a combination that speeds up front sight acquisition even in transitional lighting. The front surface of the rear sight is steeply hooked so it can be used to rack the slide one-handed in an emergency. Green tritium lamps carry a 12-year warranty from date of manufacture, and Trijicon recommends professional installation.
