The Truglo TFX Suppressor Height Sight Set (brand part no. TG13GL5A) is cut for large-frame Glocks including the 20, 21, 25, 28, 29, 30, 31, 32, 37, 40, and 41, sitting tall enough to co-witness with a slide-mounted red dot. TFX technology pairs tritium with a fiber-optic front for a sight picture that stays bright day or night, and a white outline ring around the front insert pulls the eye in for a faster sight picture. The illuminating elements sit inside a hermetically sealed, chemical- and shock-resistant capsule, while the CNC-machined steel body wears a rust-proof Fortress Finish.
