Description
The R3D 2.0 is XS Sights' second-generation night sight set, and it fixes the two things people always wanted from a carry sight: more front-sight brightness and a much easier install. This orange set is cut for the Smith & Wesson M&P and M&P 2.0 optics-ready full-size and compact pistols in a suppressor-height profile, meaning the sights sit tall enough to run over a threaded barrel or serve as backup irons behind many red dots. Just measure your slide, plate, and optic first, since not every setup will co-witness.
What Makes the R3D 2.0 Front Sight So Easy to See
The whole design pushes your focus downrange. Up front you get a wide 0.145-inch Glow Dot in high-contrast orange, built around a Swiss-made tritium vial. During the day the photoluminescent dot soaks up ambient light and pops against the target; when the sun drops, the tritium takes over and glows on its own with no charging needed. The blacked-out, serrated rear cuts glare and keeps your eye from getting distracted, while black PVC rings around the rear tritium lamps sharpen the sight picture so the front dot never gets lost in the mix.
Built Like a Carry Sight Should Be
These are CNC-machined from solid steel bar stock at the XS shop in Fort Worth, Texas, then finished in Black Nitride for corrosion and wear resistance. That combination holds up to holster wear, sweat, and years of daily carry without looking beat. The rear also carries a cocking ledge on the leading edge, so you can rack the slide one-handed off a belt, holster, or hard surface if you ever need to.
Installing the R3D 2.0 on Your M&P
XS redesigned the dovetail geometry with a lead-in edge and crush zone that cuts installation force by roughly 50 percent, letting the sight slide more than a third of the way into the dovetail before it makes full contact. You can set them with a proper sight pusher or a hammer and punch, which puts a home install within reach for a lot of folks. The tritium is backed by a 12-year illumination warranty.

Frequently Asked Questions
Will the R3D 2.0 fit my S&W M&P?
This set is cut for the Smith & Wesson M&P and M&P 2.0 optics-ready full-size and compact pistols. It uses the suppressor-height profile, so the sights sit taller than standard. Confirm your specific model against the fitment before ordering.
Are these tall enough to co-witness with a red dot?
The suppressor-height design is tall enough to work as backup irons behind many optics, but it will not co-witness with every setup. You'll want to measure your sights, optic plate, and red dot together to confirm compatibility. Optic height and mounting depth vary a lot from one system to the next.
Can I install the R3D 2.0 myself or do I need a gunsmith?
XS revised the dovetail with a lead-in edge and crush zone that cuts installation force by about 50 percent, which makes a DIY install realistic for many people. You can use a sight pusher tool or a hammer and brass punch. Following the included instructions closely makes the job go smoother, and a pusher gives you the most control.
How long will the tritium glow last?
The front and rear tritium lamps are self-luminous and glow in low or no light without any charging. XS backs the tritium with a 12-year illumination warranty. The tritium will naturally dim over its lifespan, which is normal for any tritium sight.
