TruGlo TFX Glock 20/21/25/28-32/37/40-41 3-Dot Suppressor High Tritium/Fiber Optic Night Sight Set - Black Nitride

Upgrade your duty or defensive Glock with the TruGlo TFX day/night sight set, purpose-built for fast and accurate shooting in any light. The TG13GL5A is a 3-dot suppressor-height configuration engineered for Glock 20, 21, 25, 28, 29, 30, 31, 32, 37, 40, and 41 pistols, making it an ideal co-witness setup for slide-mounted red dots or suppressed carry builds.

TruGlo's TFX platform pairs Swiss tritium with a concealed fiber-optic rod, so the sights gather ambient light during the day and glow continuously at night without batteries or any light exposure. The green tritium lamps with a crisp white outline front and matching green rear deliver a high-contrast aiming picture at a glance, day or night.

The frame is CNC-machined steel finished in TruGlo's Black Nitride Fortress Finish for excellent corrosion and wear resistance. A FOCUSLOCK front sight profile promotes rapid target acquisition, while the snag-free contour keeps the pistol clearing standard holsters cleanly. Fiber diameter measures 0.074" with a 1.0" front sight length. The set is assembled in the USA and backed by TruGlo's quality guarantee.
