The Trijicon HD XR Night Sights deliver enhanced target identification and faster front sight acquisition for Glock pistols, combining a thinner front blade at 0.122 inches with a three-dot configuration featuring a green tritium front dot outlined in orange and a green tritium rear dot outlined in black. This design provides a larger field of view and quicker engagement in transitional lighting, while the rear sights wider U-shaped notch and a steeply hooked front surface support emergency one-handed slide operation, making them an ideal choice for tactical shooters and serious everyday carry alike. The front sights orange outline adds immediate contrast against backgrounds, helping the operator locate and align the sights with minimal effort, and the green tritium lamps are warranted for 12 years from the date of manufacture, ensuring long-term reliability. Note that Trijicon HD XR Night Sights are not compatible with Glock MOS pistols, and Trijicon Bright & Tough Night Sights for Glock with suppressor-height alternatives should be used in those applications. Built for Glock 17/17L/19/22 standard frame models, these sights blend durability, rapid acquisition, and repeatable accuracy in a single, professional-grade sighting system.
