XS Sights R3D 2.0 Suppressor Height Night Sights – Glock 43X/48

Description

The XS Sights R3D 2.0 takes the well-liked original R3D and sharpens every part of it for slimline Glock carry. The front sight combines a Swiss-made tritium vial with the proprietary photoluminescent Glow Dot, so the moment your eye finds the front post it glows bright green in daylight and stays lit when the lights go out. The rear runs two larger, brighter tritium lamps than the first-generation set, framed by a black PVC ring that keeps the front and rear vials from blurring together in low light. It's the kind of sight picture that just draws your focus downrange without you having to think about it.

What Makes the R3D 2.0 Different

This is a suppressor-height set, meaning the front and rear sit tall enough to clear a threaded barrel and can, and they also give you a lower-third co-witness under a micro red dot like the Holosun 507K on a slimline slide. If your optic ever goes dark or fogs over, these irons are right there as a dependable backup. The 0.170-inch wide rear notch leaves plenty of daylight on either side of the front post, which speeds up alignment when the light is bad and you need the gun on target now.

Built to Take a Beating

The R3D 2.0 is CNC-machined from solid steel bar stock and wears a BlackNitride finish that resists rust and wear far better than plain black oxide, which matters when a carry gun rides against a sweaty body all summer. The rear face is serrated with an anti-reflective lens to cut glare in bright sun, and there's a cocking ledge on the leading edge so you can rack the slide one-handed off a belt or boot if you have to.

Fitment and Install

This set fits the Glock 42, 43, 43X and 48. XS redesigned the dovetail so the 2.0 goes in with roughly half the force of the original, and plenty of folks install them at home with a sight pusher or a punch and hammer in a few minutes. If you'd rather have a gunsmith set them, that works too.
