Description
Small Glocks like the 42 and 43 come with basic factory sights that get the job done, but the front dot can wash out or disappear against a busy background. Trijicon's Fiber Sight Set fixes that with a glowing fiber optic front post that grabs light and gives your eye something bright to lock onto the instant you present the gun. The rear sight is blacked out on purpose, so nothing competes with that front reference and your focus lands exactly where it should.
What Sets the Trijicon Fiber Sights Apart
These use the same fiber optic material Trijicon builds into scopes like the battle-proven ACOG, so the aiming point is genuinely bright without being fragile. The bodies are machined and phosphated steel, so they hold up to daily carry, holster wear, and heavy range use. The front blade runs a thin .110" width with a .268" overall height, which keeps the sight picture clean and precise instead of blocking your target.
Setting Up Your Glock 42/43 Fiber Sight Set
The set ships with a .060" red fiber pre-installed up front, plus an extra red and green fiber pack in the box so you can swap to whichever color your eye picks up faster. Red tends to pop against green outdoor backgrounds while green reads brighter for a lot of folks in lower light, so it's nice having both on hand. If a fiber ever wears out down the road, replacement packs are easy to find and simple to change.
Everyday Carry and Competition Ready
Beyond the bright front, the rear sight has a steeply hooked front surface that lets you rack the slide one-handed against a belt or holster in a pinch, and the edges are rounded to cut down on snag points when carrying concealed. This set fits the Glock 42, 43, 43X, 43E, and 48, excluding MOS models. Trijicon recommends professional installation since these are steel sights that need to be drifted into the dovetail, and it's backed by Trijicon's limited lifetime warranty.

Frequently Asked Questions
What Glock models does this Trijicon fiber sight set fit?
This set is designed for Glock small-frame pistols including the 42, 43, 43X, 43E, and 48. It does not fit MOS models. Double-check your slide cut before ordering if you have a variant you're unsure about.
Does the Trijicon fiber sight set come with both red and green fibers?
Yes. It ships with a .060" red fiber already installed in the front sight, and an extra fiber pack with both red and green replacements is included in the box. That lets you try each color and go with whichever one your eye acquires fastest.
Can I install these fiber sights myself?
Trijicon recommends professional installation. These are steel sights that need to be drifted into the dovetail with a sight pusher for proper fit and windage, and the front typically needs to be secured correctly. A gunsmith or anyone with a proper sight tool can knock it out quickly.
Are these fiber sights bright enough for carry or just competition?
They work well for both. The fiber front gives you a fast, high-contrast aiming point in daylight, and the blacked-out rear keeps your focus on that front dot. The rounded rear edges and one-handed rack ledge make it a practical carry setup, though keep in mind fiber optic sights are not illuminated in the dark like tritium night sights.
