TruGlo TG231G1MC Tritium Pro Gun Sights | Green Tritium with Orange Outline Front & Green Tritium Rear

Low-light shooting demands sights you can trust in the dark, and the TruGlo TG231G1MC Tritium Pro gun sights deliver exactly that. Built on proven tritium technology and upgraded with TruGlo's PRO-level features, these night sights combine Swiss tritium brightness with practical ergonomics for defensive shooters, hunters, and tactical users who refuse to compromise on reliability when the sun goes down.

The front sight sports a distinctive green tritium element outlined in orange—a highly visible combination that helps your eye acquire the target fast, even in near-total darkness. The green tritium rear sight pairs with that front for a coherent sight picture without batteries, light exposure, or moving parts to fail. Both elements are powered by Swiss tritium, a standard for brightness and longevity in the night-sight world. The front sight includes a FOCUS-LOCK ring that lets you dial in your eye focus quickly, a small detail that pays dividends when speed matters.

Practical design runs through every choice here. The rear sight features an angled edge built for one-hand emergency operation—fire from any position if you ever need to. The U-notch rear paired with the front sight geometry gives you fast, repeatable sight alignment in poor light. FORTRESS FINISH protects the metal from corrosion and wear, and the snag-resistant profile fits standard holsters without modification. Best of all, there's no maintenance: no batteries to die at 3 a.m., no need to expose the sights to light. They simply glow, night after night, year after year.

These sights are assembled in the USA, built for shooters who need to be ready when conditions are worst. Whether you're a concealed-carry holder, a sport shooter running night courses, or a hunter in low-light terrain, the TruGlo TG231G1MC Tritium Pro sights earn their place on a serious defensive or tactical firearm.

Frequently Asked Questions

Do TruGlo tritium sights need batteries or light to work?

No. Tritium is self-luminous—it glows continuously without batteries, charging, or exposure to light. The TG231G1MC will perform in complete darkness night after night for years with zero maintenance.

What's the difference between the front and rear sights on this model?

The front sight is green tritium with an orange outline ring, which helps your eye quickly find and focus on the target. The rear sight is green tritium in a U-notch configuration. The green tritium in both allows for a clean, uniform sight picture in low light. The front sight also includes the FOCUS-LOCK ring for fast focus adjustment.

Will these sights fit my holster?

Yes—the TG231G1MC is designed with a snag-resistant profile that fits standard holsters without modification. However, holster fit can vary by manufacturer and specific model; if you have concerns about your holster, it's wise to test fit before carrying.

Can I use one-handed emergency operation with these sights?

Yes. The rear sight features an angled edge specifically designed to allow one-hand operation in emergency situations, letting you manipulate the sight with the slide or another firm surface if needed.
