Trijicon produces military tested products that are proven to be tough, reliable and best in class. These Bright & Tough
Night Sights feature all steel body construction with silicon rubber cushions that provide shock protection for the
tritium-filled glass vials that are encased in an aluminum housing. That's what keeps them glowing at night even after
thousands of rounds fired. Guaranteed to glow for 12 years from the date of manufacture. Notice the white rings around
the glowing dots that provide superior daylight visibility and the extra large front dot for quick target acquisition.
Equally impressive, they allow faster speeds as instinctive shooting - and without the need for batteries.
You can't go wrong with Trijicon....available for all Glock models and most other combat handguns.
