TruGlo TG231S2 tritium night sights combine fiber-optic and tritium technologies to deliver a bright, reliable sight picture whether you're shooting in daylight or darkness. Unlike single-technology sights that excel in one condition but falter in another, these green front and rear sights use TruGlo's patented dual-technology design to maintain consistent visibility across all lighting scenarios. The fiber-optic elements gather ambient light for daytime brightness, while the tritium vials glow independently when the sun goes down—no batteries required, no fumbling in low light.
Built from CNC-machined steel, the TG231S2 sights are tough enough for duty carry and hunting alike. The snag-resistant design means you won't catch them on your holster or gear during the draw, and the concealed fiber-optic element keeps your sight picture sharp without giving away your position to a target. These sights fit standard handgun holsters, making them a straightforward upgrade for most common pistols.
If you spend time at the range in all conditions or carry for self-defense, reliable night sights aren't a luxury—they're a fundamental safety tool. The TG231S2 eliminates the compromise between daylight speed and low-light capability, giving you confidence in your sight picture whenever you need to shoot.

Frequently Asked Questions
Do TruGlo TG231S2 sights work in complete darkness?
Yes. The tritium vials are self-illuminating and do not require light or batteries to glow. They provide reliable visibility in complete darkness.
Will these sights fit my handgun?
The TG231S2 is designed to fit standard handguns with dovetail-cut sight mounting. We recommend confirming your specific pistol model is compatible before purchase, as sight fitment varies by manufacturer.
How long do tritium sights last?
Tritium has a half-life of approximately 12 years, meaning the glow will gradually dim over time. The sights will remain functional well beyond this period, though brightness will slowly decrease.
Are these sights snag-free for concealed carry?
Yes. The TG231S2 features a snag-resistant design and fits standard holsters without catching or protruding in a way that would cause snagging during the draw.
