The TruGlo TG131ST1 TFO tritium and fiber optic sight set pairs two proven light-gathering technologies to solve a real problem: getting a fast, accurate sight picture across all lighting conditions. Front and rear sights work together to deliver consistent brightness whether you're shooting in bright daylight or low-light scenarios—no batteries required. This is the kind of redundant design that matters when reliability counts, and it's built on TruGlo's patented combination of tritium night sights and fiber-optic technology.
If you've ever struggled to find your sights in dim conditions or squinted through glare, you know why handgun sights matter. The TG131ST1 addresses both extremes. Fiber optics gather ambient light during the day, keeping your sight picture bright and fast-acquiring. Tritium does the heavy lifting when the sun goes down, emitting its own light so you can aim in near-total darkness. The fiber is concealed from the shooter's perspective, so it won't distract you or tip off your target. Steel construction is CNC-machined for durability, and the snag-resistant design won't catch on clothing or holster edges.
Fit and function are straightforward: these sights fit standard holsters and work with the common mounting patterns on most semiautomatic handguns. No special tools or gunsmithing required for installation on compatible firearms. If you're looking for a no-compromise handgun sight upgrade that performs in sunlight and moonlight alike, the TG131ST1 delivers the kind of practical redundancy that justifies the cost.
| Brand | TruGlo |
| Model | TG131ST1 |
| Sight Type | Tritium and Fiber Optic Front and Rear Set |
| Colors | Black frame with green tritium/fiber optic |
| Material | CNC-machined steel |
| Power Source | None (self-illuminating tritium) |
The TG131ST1 is designed to fit standard semiautomatic handgun sight mounting patterns. Verify compatibility with your specific firearm before purchase, as mounting may require professional installation depending on your gun's dovetail or other attachment system.
Yes. The tritium element emits its own light independent of external light sources, making the sight picture visible in low-light and night conditions. The fiber-optic element enhances brightness in daylight and dim conditions but relies on available light, so tritium is the primary low-light performer.
No. The fiber-optic technology is concealed from the shooter's view, so it won't interfere with your sight picture or distract you during aiming.
No batteries required. Tritium night sights are self-illuminating and require no external power or ongoing maintenance to function.
