TRUGLO TFX Tritium Fiber Optic Sight Set for Glock Gen 1-5 (17, 19, 22-27, 33-35) - Green with White Front Dot Outline

The TRUGLO TFX Tritium Fiber Optic Sight Set is a dual-illumination solution for Glock Gen 1-5 pistols (models 17, 19, 22–27, 33–35) that combines tritium night glow with fiber-optic day brightness. Unlike iron sights that rely on a single light source, the TFX pairs Swiss-quality tritium—which self-illuminates without batteries—with visible fiber-optic elements to keep your front sight picture sharp in dim light, darkness, and bright sunlight alike. The green rear sight with white-outlined front dot encourages your eye to naturally settle on the front sight, speeding up your shot alignment whether you're training at the range, carrying for personal defense, or hunting in variable light conditions.

Built for reliability in the field, these sights use a snag-resistant design that won't catch on holster fabric or gear during the draw. The illuminating elements sit inside a shock-resistant capsule impervious to oils, solvents, and the rigors of ultrasonic cleaning—meaning they'll hold up to years of hard use without dimming or degrading. CNC-machined steel bodies are finished with Truglo's FORTRESS FINISH, a rust-proof protective coating that stands up to moisture, corrosion, and the occasional fumbled maintenance session.

Installation is straightforward on any compatible Glock, and the sight radius and dimensions are engineered to work with all standard holsters. If you shoot a modern Glock and want sights that work around the clock without batteries or fidgeting, the TFX delivers visibility and durability at a real-world price point.

Frequently Asked Questions

Will these sights fit my Glock model?

The TFX Sight Set is compatible with Glock Gen 1–5 frames in the following models: 17, 19, 22, 23, 24, 25, 26, 27, 33, 34, and 35. Check your Glock's model number before ordering; if you're unsure, reach out and we'll confirm fit.

Do these sights need batteries?

No. The tritium component is self-illuminating and requires no power source. The fiber-optic elements are passive and gather available light. Together, they keep your sights visible from pre-dawn through dusk and in darkness—24/7, without charging or replacing batteries.

Can I use these sights with my regular holster?

Yes. The TFX Sight Set has a snag-resistant design and is dimensioned to work with standard Glock holsters. You won't need to swap to a specialty holster to carry with these sights installed.

What happens if I accidentally expose the sights to chemicals or ultrasonic cleaning?

The illuminating elements are encased in a shock-resistant capsule that's impervious to oils, solvents, and ultrasonic cleaning processes. The steel is also protected by the FORTRESS FINISH rust-proof coating, so accidental exposure to cleaning chemicals or moisture won't degrade performance.
