The TruGlo TFO Tritium & Fiber Optic Sight Set brings reliable low-light and daylight performance to your Ruger LC9, LC9S, or 380 with a hybrid sighting system designed for everyday carry and defensive shooting. This sight set pairs a green tritium and fiber optic front sight with a yellow tritium and fiber optic rear sight, giving you fast target acquisition in bright conditions while maintaining visibility when the sun goes down. Whether you're at the range, in the field, or carrying for personal defense, TFO sights adapt to your lighting—no batteries required, no adjustments needed.
Tritium tubes glow passively in darkness, powered by radioactive decay, while fiber optic elements gather ambient light to brighten your sight picture during the day. The combination means your front and rear sights stay visible from dawn to dusk and into low-light scenarios. The green-over-yellow configuration is a time-tested contrast that helps your eye naturally settle on the front sight, the critical aiming reference. Installation is straightforward on compatible Ruger platforms, and these sights hold up to the recoil and handling demands of a carry gun.
TruGlo has built a solid reputation for tritium and fiber optic sights that don't fail when you need them. This set delivers on durability and performance without gimmicks—just physics and proven design. If you shoot your defensive handgun in variable light or simply want sights that work faster than standard notch-and-post, TFO sights are worth the upgrade.

Frequently Asked Questions
Will these sights work on my Ruger LC9S?
Yes, this TFO sight set is designed for Ruger LC9, LC9S, and 380 models. Verify compatibility with your specific firearm before purchase.
Do I need batteries for these sights?
No. The tritium component is self-luminous and requires no batteries or charging. Fiber optic elements gather existing light and require no power source.
Why is the front sight green and the rear yellow?
The green-over-yellow contrast is designed to help your eye naturally focus on the front sight, which is your primary aiming reference. This configuration speeds target acquisition and promotes proper sight alignment.
How long do tritium sights last?
Tritium has a half-life of approximately 12 years, meaning it will remain usable well beyond that period at reduced brightness. The fiber optic elements have no wear-out period and will perform indefinitely if not physically damaged.
