TruGlo TG231R2 Tritium Night Sights | Green Tritium Front & Rear Sights for Enhanced Visibility

Low-light shooting demands sights you can trust in the dark, and TruGlo TG231R2 tritium night sights deliver exactly that. These green tritium front and rear sights are built for shooters who need reliable aiming points when ambient light fades—whether you're hunting predators at dusk, running a home-defense drill, or training after sunset. The tritium gas vials glow without batteries or charging, giving you a consistent sight picture in conditions where standard iron sights become nearly invisible.

TruGlo engineered these sights with CNC-machined steel construction to handle the recoil and handling that come with serious shooting. The snag-resistant design means you won't catch your sights on holster material or gear when you draw, a practical detail that matters in real-world carry. Because they're designed to fit standard holsters, you can swap them onto most common platforms without worrying about fitment surprises.

If you shoot in low-light conditions regularly—whether for hunting, sport shooting, or defensive training—tritium night sights transform your ability to acquire a fast, confident sight picture. The green tritium option delivers bright, instantly visible aiming points that keep your focus where it needs to be.

Frequently Asked Questions

What firearms are these tritium night sights compatible with?

The TG231R2 is designed to fit standard holsters and work with common pistol mounting systems. Check your specific firearm's manual or consult with your gunsmith to confirm fitment, as sight installation often requires professional gunsmithing.

How bright are these tritium sights in complete darkness?

These sights use bright tritium gas vials that glow without external power. Brightness is consistent day after day, though tritium brightness gradually diminishes over many years. In complete darkness, the glowing vials provide enough contrast to establish a sight picture when your eyes are adapted.

Will these sights work with standard holsters?

Yes—the snag-resistant design and standard geometry allow these sights to fit with most common holsters designed for standard iron sights without any modifications.

Do I need special ammunition or optics to use these sights?

No. These are passive tritium sights that work with any ammunition your firearm handles. They're iron sights and work independently of optics, though some shooters use them as backup sights alongside mounted scopes or red dots.
