The Meprolight USA Hyper-Bright Tritium Sight Set brings self-illuminated aiming to your handgun without batteries, switches, or the need to charge anything. This green/orange front and green/black rear sight configuration uses tritium to deliver visibility across the full spectrum—from bright daylight to low-light and night shooting. Whether you're training at the range, carrying for self-defense, or running a duty gun, having sights that work in any light condition removes one variable from the equation.
The contrasting colors between front and rear sights help your eye find the front sight faster during target transitions. The bright colored front ring pulls your focus exactly where it needs to be, speeding up your sight picture and follow-up shots. Because there's no battery to die or technology to fail, these sights are ready whenever you reach for the gun—no maintenance, no worrying if they'll work in the dark.
Meprolight's Hyper-Bright formulation is designed to cut through glare and low-light situations with genuine brightness, not just a faint glow. The sights are built tough for hard use, whether that's competition, personal protection, or duty carry. If your handgun's stock sights leave you guessing in dim light or you want faster target acquisition in rapid-fire scenarios, tritium sights are a proven upgrade.

Frequently Asked Questions
Will these sights work on my handgun?
The Meprolight Hyper-Bright Tritium Sight Set Model 402203131 is a fixed sight set. Fit depends on your specific handgun model and sight cut. Verify compatibility with your firearm manufacturer or a gunsmith before purchase.
Do I need to replace or recharge the tritium?
No. Tritium is self-powered and requires no batteries, charging, or activation. The sights are ready to use whenever you need them.
How long do tritium sights stay bright?
Tritium has a long lifespan, but like all radioactive materials, it gradually decreases in brightness over time. The sights will remain functional and visible for many years of use.
What's the difference between the front and rear sight colors?
The green/orange front paired with the green/black rear creates contrast that helps your eye lock onto the front sight faster. This contrasting design aids in rapid target acquisition across different lighting conditions.
