Glock 42/43/43X – Tritium/Fiber-Optic Sight Set – TFX Pro – Orange Front Ring
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
TRUGLO’s TFX Pro sight set gives slimline Glock pistols a serious day-and-night upgrade with sealed tritium lamps, fiber-optic illumination, and a high-visibility orange Focus-Lock front ring that helps your eye grab the front sight fast. This is a steel, carry-friendly setup built for people who want more visibility than factory sights without turning a working gun into a snaggy mess.
The TFX Pro line is built for hard use. You get a square front, U-notch rear, durable protective finish, and a sight picture that still works in bright daylight, dim interiors, and real low-light conditions.

What it does
This sight set replaces the factory sights with a tritium and fiber-optic system that stays visible around the clock. The front sight uses a green tritium/fiber unit with an orange outline for faster front-sight pickup, while the rear uses a green tritium/fiber U-notch arrangement for quicker alignment and cleaner tracking under speed.
Why it’s worth it
If you want a premium slimline Glock sight upgrade that works in bright daylight, low light, and ugly real-world carry conditions, this is one of the stronger options in the lane. The fiber/tritium combo tends to be faster than plain tritium for many shooters, and the steel body is built to shrug off normal carry abuse, oils, and cleaning solvents.

Install notes
After install, confirm alignment and verify point of impact with live fire before trusting the pistol for carry or defensive use. Good sights still need proper fitment and testing.
Verify before you buy
Verify you are buying for a Glock 42, 43, or 43X non-MOS slide. Slimline Glock naming gets messy fast, and buying by vibe is how returns get born.
