Trijicon Bright & Tough Suppressor Night Sight Set for Glock Large Frame - 3-Dot Tritium Green with White Outline

The Trijicon Bright & Tough Suppressor Night Sight Set for Glock Large Frame delivers reliable low-light shooting with a proven three-dot design. Built for Glock models 20, 21, 29, 30, 36, 40, and 41 (including S and SF variants), these tritium green night sights with white outline rings help you shoot faster and more accurately in darkness—without batteries, electronics, or a light source. If you run a suppressor or shoot in low-light conditions regularly, quality iron sights that glow are non-negotiable, and Trijicon's Bright & Tough line has earned its reputation among serious shooters.

The engineering here is straightforward and robust. Each tritium lamp sits in a metal body, cushioned by silicone rubber to absorb recoil shock. A sapphire jewel caps every lamp, distributing light evenly and shielding it from solvents and impact. The aluminum cylinders that house the lamps add another layer of protection, so these sights can handle the abuse that comes with hard use. Three-dot sight geometry is instinctive—front sight focus, quick target acquisition, repeatable hits—and the bright green tritium makes that front sight glow even when ambient light is gone.

Trijicon backs the green lamps with a 12-year warranty from manufacture, which tells you something about the durability you're getting. These aren't budget sights; they're a core upgrade for shooters who won't compromise on low-light capability or reliability. Pair them with your large-frame Glock and you'll have a night-capable pistol that doesn't depend on a mounted light or your eyesight holding up in the dark.

What's included in this sight set?

This is a complete sight set that includes both front and rear sights in the three-dot configuration.

How long will the tritium stay bright?
