The Truglo TFX Suppressor Low Sight Set (brand part no. TG13GL4A) fits standard-frame Glocks including the 17, 17L, 19, 22, 23, 24, 26, 27, 33, 34, 35, 38, and 39, giving that lineup a co-witness-height iron sight built around Truglo’s TFX tritium/fiber-optic hybrid technology. A white outline ring around the front insert draws the eye in fast, while the CNC-machined steel body carries a rust-proof Fortress Finish and a hermetically sealed capsule that shields the tritium from oils, chemicals, and ultrasonic cleaning. The result is a sight that reads the same in bright daylight or total darkness, no battery required.
