Meprolight Tru-Dot Black Night Sights - Green Tritium Front & Yellow Tritium Rear (102223201)

The Meprolight Tru-Dot Black Night Sights deliver reliable low-light aiming when conventional sights fail. This green tritium front and yellow tritium rear sight set uses self-illuminating gas tubes—no batteries, switches, or electronics to maintain or depend on. The high-contrast green front blade stands out clearly against the yellow rear for a quick, intuitive 3-dot sight picture in darkness, dim conditions, or glare. Whether you're training after hours, responding to a home threat, or hunting in the predawn woods, these sights perform when lighting conditions challenge standard sights.

Meprolight Tru-Dot sights are built to mil-spec standards and see service with NATO, U.S., and Israeli armed forces, plus law enforcement and serious civilian shooters who demand accuracy in challenging light. The robust black finish resists corrosion, and tritium illumination is immune to gun solvents, oils, and weather—your sights will work the same way in the rain, dust, or heat as the day you install them. The 12-year manufacturer warranty backs your investment from the original owner forward.

Fit varies by platform: front sights either replace the original blade directly (1911-style), pin over the existing front blade (most modern autos), or swap a colored factory insert (some S&W automatics). Rear sights replace the factory rear sight completely or, on S&W revolvers, install as a new rear leaf with supplied screws and hardware. Check your specific model's requirements before ordering to confirm fit.

Frequently Asked Questions

What handgun models do these Meprolight night sights fit?

Meprolight Tru-Dot sights are made for multiple platforms. Installation method varies: they replace the original front blade on 1911-style pistols, pin over the existing blade on most modern autos, or swap into an insert slot on some S&W automatics. Rear sights either replace the factory rear entirely or install as a new rear leaf assembly (particularly on S&W revolvers). Verify compatibility with your specific handgun model before purchase.

How long do tritium night sights stay bright?

Tritium is a radioactive isotope that self-illuminates continuously without any external power. The glow does gradually fade over time, but these sights are engineered for years of reliable low-light performance. The 12-year manufacturer warranty reflects Meprolight's confidence in durability and illumination quality.

What's included in this set?

This package includes both a green tritium front sight and a yellow tritium rear sight, giving you a complete sight replacement set. Depending on your handgun platform, mounting hardware (screws, nuts, or pins) may be included to facilitate installation on your specific model.

Are these sights affected by gun oil, solvents, or moisture?

No. Meprolight Tru-Dot sights are sealed and corrosion-resistant; gun solvents, oils, and water do not degrade the tritium tubes or sight performance. They maintain the same brightness and function in rain, dust, extreme heat, or after exposure to standard firearm cleaning and maintenance products.
