TruGlo TFO TG131GT1B Night Sight Set for Glock 42/43/43X/48 - Green Front/Yellow Rear - Low Profile

The TruGlo TFO TG131GT1B night sight set pairs self-illuminating tritium inserts with ambient-light-gathering fiber optics in a single low-profile package for slimline Glock pistols. The fiber optic elements brighten the sight picture in daylight, while the tritium glows without batteries or switches at night, giving you a dependable aiming reference around the clock.

Both front and rear elements are built on CNC-machined steel housings finished in TruGlo's Black Nitride Fortress coating for corrosion resistance and long service life. The low-profile design helps the sights co-witness with many slide-mounted optics and reduces snag during the draw. The contrasting color scheme pairs a green fiber optic/tritium front with a yellow fiber optic/tritium rear so the eye locks onto the front sight quickly and intuitively.

The TG131GT1B is engineered specifically for the slimline Glock platform and fits the Glock 42, Glock 43, Glock 43X, and Glock 48 - MOS variants are excluded. Installation uses the standard factory dovetail cuts on the slide, no permanent modification required. For shooters who carry or train with one of these pistols, the TruGlo TFO delivers proven day-and-night performance without the bulk or battery dependence of an electronic sight.
