The Meprolight USA Tru-Dot Black Tritium Sight Set brings reliable low-light performance to your handgun without batteries, electronics, or moving parts. This green front and orange rear tritium sight set uses self-illuminating gas light sources built into both blades to deliver a crisp 3-dot sight picture in darkness, dawn, dusk, and overcast conditions—situations where standard sights leave you squinting. Trusted by NATO forces, U.S. military units, and Israeli defense personnel, Tru-Dot sights have proven themselves in the field and on the street for decades. If you carry a handgun for duty, sport, or defense and need fast sight acquisition when ambient light fails, tritium sights aren't luxury—they're insurance.

Unlike fiber-optic or painted sights that rely on external light, tritium sights work in complete darkness. The contrasting green front blade against the orange rear creates a naturally high-visibility sight picture without adding bulk or requiring any action on your part. Weather, gun solvents, oils, and the elements won't degrade the self-illuminating tritium; it simply continues to glow for years. There's no on/off switch to fumble, no battery to run dead when you need it most, and no maintenance beyond normal handgun care.

Installation depends on your specific handgun model. Some Tru-Dot sets replace the original front and rear sights entirely (common on 1911s); others slip over and pin to the existing front blade while the rear installation varies. S&W revolver models receive a new rear leaf, screw, and nut, while S&W autos use a front sight that replaces the factory colored insert. Confirm your handgun's compatibility before ordering. Meprolight backs this product with a 12-year manufacturer warranty to the original purchaser, reflecting confidence in the durability of tritium illumination.
