The XS Sights R3D 2.0 for Sig P320 with suppressor-height and green tritium is a second-generation night sight built for shooters who demand speed and precision in any light. Engineered to be 50% easier to install than the original R3D, this set combines traditional 3-dot sight geometry with dual-illuminated tritium and photoluminescent technology, giving you a sight picture that stays visible whether you're shooting in bright daylight or complete darkness. The green tritium front sight pairs with a serrated, blacked-out rear to keep your focus downrange, while the suppressor-height design clears most pistol-mounted optics and cans.

Built in Fort Worth, Texas, the R3D 2.0 is engineered to handle years of carry and hard use. The Black Nitride finish resists corrosion and abuse, and the wide rear notch with anti-reflective lens reduces glare when you need it most. Whether you're training at the range, running a defensive scenario, or carrying for everyday protection, this sight set delivers the brightness and contrast that lets you drive accurate shots fast.

Installation is straightforward—the 50% reduction in required force compared to first-gen R3D sights means faster, easier installation on your Sig P320 without strain or risk of damage. The photoluminescent glow dot absorbs ambient light and glows in low-light conditions, giving you a backup sight picture when tritium isn't enough.

Frequently Asked Questions

Will these sights work with my Sig P320 and a suppressor-mounted optic?

Yes. The R3D 2.0 is cut to suppressor-height, which means they sit taller than standard sights and clear most common pistol-mounted red dots and suppressors.

What's the difference between the tritium and photoluminescent elements?

The tritium glows on its own in darkness and requires no charging—it provides a consistent sight picture 24/7. The photoluminescent glow dot absorbs ambient light during the day and glows in low-light conditions, giving you two layers of visibility.

How much easier is installation on the R3D 2.0 compared to the original?

The R3D 2.0 requires approximately 50% less installation force than the first-generation R3D sights, making the install faster and less strain on your hands or sight pusher tool.

What sight picture does the R3D 2.0 use?

The R3D 2.0 uses a traditional 3-dot configuration with a notch and post geometry. The front sight is green tritium, and the rear is a wide serrated notch with a blacked-out profile to keep your focus downrange.
