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

If you're running a full-size Glock and want reliable target acquisition in low light without fumbling for a flashlight, the Trijicon Bright & Tough Suppressor Night Sight Set delivers. These are three-dot tritium night sights engineered for large-frame Glocks (Models 20, 21, 29, 30, 36, 40, and 41, including S and SF variants), with green tritium lamps accented by a white outline on the front sight. No batteries, no electronics—just self-luminous sights that work when you need them, whether you're hunting at dawn, shooting late at the range, or training in dim conditions.

The design is built tough. Each tritium lamp sits inside a metal body cushioned by silicone rubber, paired with shock-resistant construction that handles heavy recoil without degradation. The lamps themselves are capped with sapphire jewels that distribute light evenly and shield the tritium from solvents, impact, and puncture. This matters if you're serious about your firearm—you need sights that survive field use and cleaning without losing brightness or precision.

Trijicon's tritium technology has a track record. The green lamps are warranted for 12 years from manufacture, a real confidence signal in a consumable component. The three-dot configuration mirrors instinctive aiming, so you get the same speed as natural shooting while gaining a significant low-light advantage—studies show tritium sights can improve accuracy by as much as five times in darkness compared to conventional iron sights.

Frequently Asked Questions

Will these sights fit my Glock?

Yes, if you own a large-frame Glock Models 20, 21, 29, 30, 36, 40, or 41 (including S and SF variants). If you have a compact or subcompact Glock, you'll need a different sight set.

Do I need batteries or charging for these sights?

No. Trijicon tritium night sights are self-luminous and require no batteries, charging, or external power. The tritium lamps glow continuously and are always ready to use.

How long do the tritium lamps last?

Trijicon warrants the green tritium lamps for 12 years from the date of manufacture. Tritium does decay over time, but the sights will remain visible well beyond the warranty period.

What's the difference between the three-dot setup and other configurations?

Three-dot sights—two rear dots and one front dot—mirror instinctive aiming mechanics, allowing fast target acquisition at close to intermediate range with the same natural sight picture as regular iron sights, but with tritium glow for low-light use.
