The Trijicon HD XR Night Sights for Glock MOS deliver a refined green tritium illumination with an orange front sight and a black rear, built to meet the evolving demands of law enforcement and serious handgun shooters alike. Specifically designed to fit Glock models including 17MOS, 19MOS, 34MOS, and a wide range of standard frames, this 3?dot sight set features a thinner front post that broadens the field of view for quicker target identification and faster engagements at extended distances, while still providing precise hit location in low light. The HD XR design enhances night visibility and target identification through a sharper sight picture, enabling more reliable engagements when lighting is challenging. Green tritium lamps are warrantied for 12 years from the date of manufacture, offering long?term confidence in performance. With a matte finish that reduces glare, these sights integrate seamlessly with Glock MOS pistols, delivering an unobtrusive, high?contrast silhouette that supports fast acquisition, aim stability, and consistent sight alignment across a variety of duty and sporting scenarios.
