TruGlo TGTG231N4 Tritium Night Sights - Green Tritium Front & Rear Sights

The TruGlo TGTG231N4 tritium night sights deliver reliable low-light aiming when your pistol needs to work in darkness. These green tritium night sights pair a green tritium front sight with a green tritium rear sight, giving you a consistent sight picture whether you're shooting in a dimly lit range, on night duty, or in any scenario where ambient light fades. Unlike conventional sights that disappear after sunset, tritium sights glow continuously without batteries—a proven technology trusted by shooters who can't afford to guess at their sight alignment when visibility drops.

Tritium night sights work through self-illumination: tiny vials of tritium gas inside the sight posts emit a faint, steady glow that your eye can pick up in near-total darkness. The green color TruGlo has chosen for both the front and rear elements creates a cohesive sight picture and is easier on the eyes during extended low-light shooting. Because tritium requires no external power source, these sights will keep working long after your flashlight batteries die—making them an honest addition to any defensive, duty, or night-hunting setup.

Installation does require gunsmithing knowledge or a professional sight pusher; these are direct replacements for factory sights on compatible pistols, but they're not a bolt-on upgrade. Once installed, tritium sights require zero maintenance and will perform in any weather. The glow gradually fades over many years (tritium has a roughly 12-year half-life), but for the working life of most firearms, you'll have reliable illumination right when you need it.

Frequently Asked Questions

What pistols are these night sights compatible with?

The TruGlo TGTG231N4 is designed as a direct replacement for factory sights on compatible handguns. Check the model number against your pistol's documentation or contact us to confirm fit before purchasing.

Do tritium night sights require batteries?

No. Tritium is a radioactive isotope that self-illuminates through natural radioactive decay. These sights glow continuously without any external power source, making them reliable in any condition.

How long do tritium sights stay bright?

Tritium has a half-life of approximately 12 years, meaning the glow will gradually fade over that timeframe. For most shooters and working firearms, you'll have plenty of usable light during the effective service life of your gun.

Can I install these myself?

These sights require removal of your factory sights and precise installation. A gunsmith or professional armorer with a sight pusher tool is the safest way to install them correctly and avoid damage to your pistol's slide.
