XS Sights F8 Night Sight Set for Glock 42 & 43 – Green Tritium

Description

The XS Sights F8 is built around one simple idea: your eyes go where the contrast is, so make the front sight impossible to miss. That large orange front ring wrapped around a green tritium lamp grabs your focus fast in daylight, and the photoluminescent material soaks up ambient light to keep glowing when the sun drops. Pair that with a wide U-notch rear and you get a sight picture that comes together quick, whether you're punching paper at the range or reaching for your Glock in the dark.

How the F8 Figure-8 Sight Picture Works

The "F8" name comes from the shape you see when everything lines up. Stack the round front dot over the round rear dot and you get a figure-8, which is a dead-simple way to confirm your alignment under stress. The base of the rear notch is rounded to pull your eye up to the top edge where it belongs, and the rear sight overhangs slightly toward you to knock down glare in bright sun. There's also a flat ledge on the rear that lets you rack the slide one-handed off a belt or boot if you ever need to.

Fitment and Install for the Glock 42 & 43

This set is cut for the Glock 42, 43, 43X, and 48 slides, with a 0.280" front sight height and a 0.365" rear. These run a touch taller than factory Glock irons, which gives you a natural sight alignment and lets them work as backup irons under some slide-milled red dots. Both sights are machined from steel with tritium inserts front and rear, so there are no batteries to babysit. The front swaps out with a single screw and the rear drifts into the dovetail with a sight pusher or a punch and a little patience.

Everyday Carry That Stays Ready

Because the tritium glows on its own, your gun is always ready to aim in low light without you touching a thing. The profile fits standard holsters, so you're not hunting for new leather or Kydex after the upgrade. It's a clean, no-nonsense sight setup for a carry gun that pulls double duty at the range.
