Xs R3d 2.0 For Sig 320 Sup Hgt Green

The XS Sights R3D 2.0 suppressor height night sights for Sig P320 are purpose-built for shooters who carry daily and demand sights that work in any light. These second-generation tritium sights combine a traditional 3-dot sight picture with dual-illumination technology—front and rear tritium elements glow constantly in low light, while a photoluminescent coating absorbs ambient light for visibility in bright conditions. The serrated rear sight with anti-reflective lens forces your focus downrange and cuts glare, while the standard-dot front sight sits at suppressor and optic height (0.397" front, 0.445" rear), ideal if you're running a can or red dot on your P320.

Installation is notably easier than first-gen sights—XS engineered these to require 50% less force during setup, so you won't need a gunsmith or a press to swap them in. The Black Nitride finish resists corrosion through carry, cleaning, and holster wear, which matters if you're actually using your gun instead of displaying it. Built and finished in Fort Worth, TX, the R3D 2.0 sits at the bright end of the notch-and-post sight spectrum, giving you a fast, reliable aiming reference whether you're drawing at dusk or shooting steel in midday sun.

These sights are engineered for the working gun—EDC pistols, duty rigs, and range guns that see real use. If you shoot a Sig P320 and want sights that stay visible when your lights are off or your optic is obscured, or simply prefer traditional iron sights with genuine tritium backup, the R3D 2.0 suppressor height set covers both day and low-light shooting without compromise.

Frequently Asked Questions

Will XS R3D 2.0 suppressor height sights work with a suppressor or red dot on my Sig P320?

Yes. These sights are cut to suppressor and optic height (0.445" rear, 0.397" front), so they sit lower and won't block your view through a mounted optic or get in the way of a suppressor. They're also cowitness-capable if your red dot is mounted on a compatible slide racker.

Do I need a gunsmith to install the R3D 2.0 sights?

No. The R3D 2.0 requires 50% less installation force than the original R3D, so a standard sight pusher tool or even manual installation with a drift punch is realistic for most shooters. That said, if you're not comfortable working on your pistol, any gunsmith can install them quickly.

How long do the tritium sights stay visible in the dark?

Tritium is self-illuminating and glows continuously without batteries. The photoluminescent front sight also absorbs ambient light during the day and releases that glow in darkness. Both work together to keep your sight picture visible across a wide range of lighting conditions.

Are these sights durable for everyday carry?

Yes. The Black Nitride finish is engineered for corrosion resistance, and the sights are designed to withstand the wear of daily EDC, holster rubs, and regular cleaning. The rugged notch-and-post design is also less prone to damage than some sight styles.
