Trijicon Suppressor Height Sights Green Tritium White Outline Front and Rear Glock 20 21

The Trijicon 600689 Suppressor/Optic Height Sights deliver a robust, three-dot night sight system with Green/Tritium White Outline front and rear sights designed for Glock 20/21 large frame pistols (including S and SF variants). These Bright & Tough Night Sights are engineered to dramatically improve night-fire accuracy, potentially increasing performance up to five times over traditional sights, while maintaining instinctive-speed aiming without batteries. Housed in a solid metal body and cushioned within silicone rubber, the sights feature a shock-resistant, sapphire-jewel lamp design that distributes light evenly and protects the lamps from solvents and punctures. The lamps are secured in aluminum cylinders and mounted on silicone cushions to withstand heavy recoil, making them well-suited for high-use pistols in demanding conditions. The Green lamps are warranted for an extended service life, providing reliable visibility in low-light environments. For shooters seeking fast target acquisition, enhanced accuracy, and a durable, weather-resistant sighting solution on Glock models 20/21 and related large-frame variants, this Trijicon sight set offers a proven, ready-to-use upgrade for precision shooting and defensive applications.
