The Trijicon HD XR Night Sight Set in Orange Front Outline for Glock Models 42 & 43 delivers a refined, competition-ready upgrade for tactical and duty use, featuring a thinner front sight (0.122) to widen the field of view, which helps identify targets faster, expedite engagements, and clearly see hit location at longer distances. This three-dot green tritium sight set combines a taller front blade with a photoluminescent ring for an aiming point and a rear sight outlined in black with a wider U-shaped notch, enhancing visibility and rapid front sight acquisition even in transitional lighting. The front surface of the rear sight is designed with a steep hook to assist one-handed slide operation during emergencies, while the Orange Front outline provides a high-contrast pointing plane for quick targeting. These sights are specifically designed for Glock 42/43 and are not compatible with Glock MOS platforms; for Glock configurations using suppressor-height sights, Trijicon Bright & Tough Night Sights are recommended. Green tritium lamps are warranted for 12 years from the date of manufacture, offering long-lasting visibility in low-light scenarios.
