Meprolight Tru-Dot Black Front Sight | Green Tritium with Black Outline (Model 102243107)

The Meprolight Tru-Dot Black Front Sight with green tritium is a self-illuminated night sight upgrade designed to improve your accuracy in all light conditions. This front sight features a green tritium dot with a black outline, giving you a consistent aiming point whether you're shooting in bright daylight, low light, or complete darkness. Unlike traditional iron sights that become difficult or impossible to use once the sun sets, tritium sights glow on their own, letting you maintain sight picture and shot placement when ambient light fails.

Built on Meprolight's decades of combat-proven design, the Tru-Dot system keeps your aiming reference identical in appearance and location across day and night shooting. You won't need to adjust your technique or transition your sight picture—the three-dot alignment works the same whether you're at the range at noon or responding to a threat in darkness. Meprolight's manufacturing is certified to ISO-9001:2008 and complies with NATO and US Military specifications, which is why these sights are trusted by law enforcement and military users worldwide.

This front sight is engineered as a direct replacement for your handgun's existing front sight, though minor modifications may be required depending on your specific firearm model. The combination of green tritium and black contrast makes the sight fast to acquire and smooth to transition between targets. If you regularly train after dark, carry for personal defense, or hunt in low-light conditions, self-illuminated night sights are one of the highest-return upgrades you can make to your handgun's capability.

Frequently Asked Questions

Will this front sight work on my handgun?

The Tru-Dot front sight is designed as a direct replacement for standard handgun front sights. Minor modifications may be required depending on your firearm model. We recommend checking compatibility with your specific handgun before purchase or consulting with a qualified gunsmith.

Do I need to replace both front and rear sights for the Tru-Dot system to work?

This is a front sight only. Meprolight offers matching rear sights in various tritium colors (green, yellow, and orange on selected models). Many users pair this green front sight with a matching or contrasting rear sight for optimal sight picture.

How long do tritium sights stay illuminated?

The product information provided does not include tritium lifespan details. Contact Meprolight directly or consult the product documentation for specific information on tritium duration.

What's the advantage of self-illuminated sights over traditional iron sights?

Traditional iron sights rely on ambient light to be visible—in darkness or low light, they become difficult or impossible to use. Tritium sights glow on their own, allowing you to maintain sight alignment and accuracy in conditions where conventional sights fail. This is critical for home defense, duty carry, and low-light hunting scenarios.
