Frequently Asked Questions
Will this plate work with all variants of the SIG P320, or only specific models?
This adapter plate is specifically designed for the SIG P320 RX, P320 Pro Series, and P320 AXG slide configurations, which share a compatible optic cut footprint. It is not intended for standard P320 slides that lack the factory optic-ready cut. If you're unsure which slide variant you have, check the markings on your slide or consult your owner's manual before ordering.
Which Holosun optics are compatible with this adapter plate?
This plate is designed to interface with the Holosun 407K and Holosun 507K compact red dot sights. These are sub-compact footprint optics commonly used on micro and compact pistols. Other Holosun models with a different footprint — such as the 507C or 509T — are not compatible with this specific plate.
Does installing this adapter plate affect my pistol's warranty or require permanent modification?
This is a drop-in adapter plate that mounts using the existing optic-cut on your P320 RX, Pro Series, or AXG slide — no drilling, milling, or permanent alterations are required. However, any modification to your firearm may have implications for your manufacturer's warranty. C&H Precision recommends following the included installation instructions carefully and using a proper torque driver to avoid over-tightening the stainless steel mounting screws.
