TruGlo TFX Glock 20/21/25/29/30/31/32/37/40/41 High Set Tritium/Fiber Optic Night Sights - Black Nitride

The TruGlo TFX Glock High sight set combines tritium and fiber-optic technology in a self-illuminating, snag-resistant 3-dot configuration engineered for low-light carry and defensive use. Built around TruGlo's TFX platform, each lamp pairs Swiss-made tritium vials with high-contrast fiber-optic elements, so the dots stay visible in bright daylight and continue to glow at night without batteries or a light source.

The frames are CNC-machined from steel and finished in TruGlo's Black Nitride Fortress Finish for serious wear and corrosion resistance. The front sight carries a green tritium and fiber-optic insert ringed by a white outline for fast target acquisition, while the rear uses a matching green tritium and fiber-optic setup in a square-notch blade designed to draw the eye back to the front post quickly.

Designed as a High Set for full-size Glock pistols, this TFX fits the Glock 20, 21, 25, 29, 30, 31, 32, 37, 40, and 41 in standard, non-MOS configuration. The low-profile, snag-free shape rides cleanly in standard holsters, and the tritium vials are rated to deliver reliable illumination for up to 20 years of service life.
