Meprolight Tru-Dot Black Tritium Sight Set - Green Front & Rear Sights (USA 177753101)

The Meprolight Tru-Dot Black Tritium Sight Set delivers reliable low-light aiming when conventional sights fail you. This green front and rear sight combination uses self-illuminating tritium gas tubes—no batteries, no buttons, no on/off switches—to produce a bright green 3-dot sight picture in darkness, dim indoor ranges, or dawn/dusk conditions. Because tritium is passive and always-on, you get instant visibility without fumbling for activators or worrying about power running out mid-hunt or during a defensive situation.

Meprolight tritium sights have earned trust with NATO, U.S. military, Israeli Defense Forces, and professional law enforcement for decades. The sight set includes both front and rear blades, each with its own tritium light source. The green front sight delivers contrast against the green rear sight, making the 3-dot picture fast and intuitive to acquire. These sights are sealed and unaffected by gun oils, solvents, water, or temperature swings—they keep working whether you're hunting in cold rain, shooting on a dusty range, or relying on them for home defense.

Installation varies by firearm: front sights may replace the factory blade directly (1911 style), slip over and pin to the original (most modern autos), or replace a colored insert (some S&W autos). Rear sights either replace the existing rear sight entirely or, on revolvers, install via a new leaf, screw, and nut. Check fit with your specific handgun before ordering. The manufacturer backs these sights with a 12-year warranty to the original buyer.

Will these tritium sights work on my handgun?

Meprolight makes TRU-DOT sights for a wide range of handguns including 1911 autos, most modern semi-auto pistols, and S&W revolvers. Installation method depends on your firearm: some sights replace the original blade, others pin or slip over existing hardware, and some replace factory colored inserts. Check compatibility with your specific model before ordering.

Do I need batteries or a switch to use these sights?

No. These are completely passive. Tritium gas tubes are self-illuminating and always on. There are no batteries to replace, switches to activate, or charging required. They work in any light condition, from bright daylight to total darkness.

What's included in this sight set?

The set includes both front and rear sights, each with its own tritium light source. Depending on your firearm, the rear sight may include mounting hardware (screw and nut for revolver leaf installation, for example) as needed to fit your gun.
