- Converts R1P or DPP-cut slides to accept RMR, SRO, and Holosun optics
- Compatible with SIG P320 RX Series, Pro Series, and AXG Scorpion models
- Precision-machined from aerospace-grade 6061 aluminum for strength and durability
- Includes stainless steel mounting hardware for long-term corrosion resistance
- Machined on HAAS CNC equipment to the tightest possible tolerances
- Proudly designed, manufactured, and quality-checked in the USA
Who This Is For
This adapter plate is ideal for SIG P320 owners who want to upgrade from their factory Romeo1 Pro or DPP optic cut to a more widely supported Trijicon or Holosun footprint. Whether you're a competitive shooter chasing a faster red dot, a duty carrier standardizing on Trijicon RMR, or a home-defense enthusiast adding a Holosun 507C, this plate delivers a solid, zero-shift-free mounting solution without permanently altering your slide.

Frequently Asked Questions
Which SIG P320 models and existing slide cuts does this adapter plate support?
This plate is specifically designed for SIG Sauer P320 pistols that already have a Romeo1 Pro (R1P) or DPP optic cut from the factory. Compatible models include the P320 RX Series, P320 Pro Series, and the P320 AXG Scorpion. If your slide has a different factory cut — such as the XRAY or standard optic-ready cut — this particular plate is not the correct fit, and you should verify your slide's existing footprint before ordering.
Which optics can I mount using this adapter plate?
Once installed, this adapter plate accepts any optic using the Trijicon RMR/SRO footprint, which is one of the most popular and widely supported red dot mounting patterns available. Compatible optics include the Trijicon RMR (all generations), Trijicon SRO, Holosun 407C, 507C, 508C, and 508T. This makes it an excellent choice for shooters who want to run proven duty-grade or competition optics without replacing their entire slide.
Will this plate affect my zero or shift under recoil?
C&H Precision Weapons machines each plate to extremely tight tolerances using professional-grade HAAS CNC equipment, and every plate undergoes multiple quality control checks before shipping. When installed correctly with the included stainless steel hardware and proper torque specs, the plate provides a rigid, repeatable mount that resists shift under recoil. As with any optic mounting system, it is recommended to use a thread-locking compound on the mounting screws and confirm zero after installation.
