TruGlo TFO TG131GT1A Glock 42/43/43X/48 Green Tritium/Fiber Optic Night Sight Set - Low Profile

The TruGlo TFO TG131GT1A night sight set pairs fiber-optic and tritium technology to deliver a consistently bright aiming picture in any lighting for your Glock 42, 43, 43X, or 48 pistol (excludes MOS models). The TFO system gathers ambient light through the fiber-optic inserts during the day and self-illuminates via tritium in low-light or no-light situations, so both the front and rear sights stay visible around the clock without batteries or switches.

Both the front and rear sights use green tritium and fiber-optic elements for a high-contrast sight picture. The frame is CNC-machined steel finished in TruGlo's Black Nitride Fortress coating for excellent wear and corrosion resistance. The sights sit in a low-profile configuration that keeps the top of the slide clean and snag-free during the draw, with a fiber diameter of 0.060" and a front sight length of 1.0".

Designed as a direct-fit replacement, this TFO set installs easily on the factory Glock dovetail and is engineered for a precise fit on the Glock 42, 43, 43X, and 48 (excludes MOS variants). Whether you carry a slim-frame Glock for personal defense or duty use, the TruGlo TFO night sight set gives you the same bright aiming reference trusted by concealed-carry and law-enforcement shooters alike.
