Description
The XS Sights R3D 2.0 set is made for the optics-ready HK VP9, and the suppressor-height blades are what make it work. That taller stack lets you keep a clean sight picture over a mounted can, and it also puts the irons up where they can co-witness through a red dot window as a backup if your optic ever goes dark. It's a smart setup for anyone running a suppressor, an optic, or both.
What Sets the R3D 2.0 Apart on the VP9
The heart of these sights is a dual-illuminated front. You get a tritium lamp for glow in total darkness wrapped in a photoluminescent Ember Glow Dot that soaks up ambient light and lights up on its own. Daytime, the high-contrast ring pulls your eye straight to the front post. Nighttime, the tritium takes over. The rear runs a wide 0.170-inch notch with serrations and an anti-reflective treatment, so you get plenty of daylight on either side of the front post for quick alignment and no distracting glare off the top of the rear blade. XS bumped up the brightness of the rear tritium on the 2.0 compared to the original R3D too, and the black PVC rings around the rear lamps keep them visually separate from the front so you're not chasing three identical dots.
Built to Take Carry and Range Miles
These are steel sights finished in corrosion-resistant Black Nitride, made in Fort Worth, Texas. XS designed the front blade with a ledge that helps with one-handed slide manipulations off a belt or boot, which is a nice touch for a defensive gun. The traditional notch-and-post picture is one most folks already shoot fast, so there's no relearning your fundamentals.
Installing Your R3D 2.0 Sights
Installation is a common point people ask about, and the 2.0 was engineered to go in with roughly half the force of the original. You can push them in with a sight tool or tap them with a hammer and punch. Just take it slow and protect your slide finish. The kit comes with everything you need for a DIY job.

Frequently Asked Questions
Will the R3D 2.0 suppressor height sights co-witness with my red dot?
The taller suppressor-height blades are designed to sit high enough to be seen through most optic windows on the VP9 OR, which lets them serve as a backup if your dot fails. That said, co-witness height depends on your specific optic, mounting plate, and how they stack together. Measure your setup before ordering to confirm the sights, plate, and optic all line up the way you want.
Do I need a suppressor to use these sights?
No. The suppressor height is popular for two reasons: it clears the top of a mounted can, and it raises the irons enough to co-witness behind a red dot. Plenty of folks run these on an optics-ready VP9 with no suppressor just for the taller backup sights.
How hard is it to install the R3D 2.0 on a VP9?
XS built the 2.0 to install with about half the force of the original R3D, so it's a doable DIY job. You can use a sight pusher tool or a hammer and brass punch, and the kit includes red threadlocker and instructions. Go slow and protect your slide finish, since scratching the slide is the most common mistake people make.
What's the difference between the orange and green front sight?
Both front sights use the same tritium lamp and photoluminescent Ember Glow ring for identical low-light performance. The color just changes what your eye picks up in daylight. Orange tends to pop against dark or busy backgrounds, while green reads as a bit more neutral. It comes down to personal preference.
