Glock 42/43/43X/48 – Tritium/Fiber-Optic Sight Set – TFX – White Front Ring


PLEASE DOUBLE CHECK DETAILS, MODEL FITMENT, MOS COMPATIBILITY, AND INSTALLATION REQUIREMENTS BEFORE PURCHASE.

TRUGLO’s TFX sight set gives slimline Glock pistols a true day-and-night sight upgrade with tritium and fiber-optic illumination in a steel carry-ready package. This version uses a green tritium/fiber-optic front sight with a white front sight outline and green rear tritium/fiber-optic lamps, giving you a brighter sight picture without batteries, charging, or other nonsense.

This is the standard TFX setup, not the TFX Pro version. It is a strong fit for shooters who want around-the-clock visibility, durable steel construction, and a low-profile carry upgrade that still works with normal carry gear.

What It Does

This sight set replaces factory sights with a tritium and fiber-optic system that stays visible in daylight, dim interiors, and low light. The front sight uses a green lamp with a white outline to help pull your eye to the front sight faster, while the rear gives you a clean green reference without needing batteries or light exposure.

Why It’s Worth It

If you want something brighter than plain tritium and more useful in mixed lighting than basic factory irons, this is a solid carry upgrade. The TFX line is built for real-world use, with protected tritium/fiber-optic technology, steel construction, and a snag-resistant profile that plays nicely with most holsters.

Tools Needed

A proper sight pusher and the correct front sight tool are strongly recommended. This is not a hammer-and-hope job unless scratched slides and regret are your hobbies.


Verify Before You Buy

Verify you are buying for a Glock 42, 43, 43X, or 48 non-MOS slide. This is the standard TFX sight set, not the TFX Pro, not an MOS optic-height sight set, and not a standard double-stack Glock sight set. Slimline Glock naming gets messy fast, and buying by vibes is how returns get born.
