Frequently Asked Questions
Will these sights work with my SIG P320 X-Carry or P320 Compact?
Yes — the XS Sights R3D 2.0 Suppressor Height sights are designed to fit the SIG P320 platform, which includes the Full Size, Carry, Compact, and X-Series variants that share the same slide-cut dimensions. If you're unsure about your specific variant, XS Sights' compatibility tool on their website can confirm fitment before purchase.
What is the difference between the standard height and suppressor height R3D 2.0 sights?
Suppressor height sights sit taller than standard height sights, allowing the sight picture to remain visible above a mounted suppressor, compensator, or threaded barrel adapter. They can also be useful for co-witnessing with certain micro red dot sights. If you're running a factory barrel without any muzzle devices, standard height sights may be preferable for a lower, more snag-resistant profile.
How long does the tritium illumination last on the R3D 2.0 sights?
Tritium has a half-life of approximately 12 years, meaning the self-luminous glow will remain clearly visible for well over a decade of normal use. In addition to the tritium element, the photoluminescent dot on the front sight absorbs ambient and UV light and re-emits it as a bright glow — providing enhanced visibility even in conditions where tritium alone may appear dim, such as transitional lighting environments.
