The Calculated Kinetics Adapter Plate SIG320-RMR is a precision-machined mounting solution that allows SIG P320 pistol owners to install Trijicon RMR footprint red dot sights. Designed specifically for the SIG P320 platform, this adapter plate provides a secure, low-profile, and reliable interface for mounting popular optics such as the Trijicon RMR, SRO, and compatible red dot sights. Whether you’re building a competition pistol, a duty-ready firearm, or an everyday carry setup, the SIG320-RMR delivers professional-grade performance and clean aesthetics.
Why Choose the Calculated Kinetics SIG320-RMR Adapter Plate?

Unlike generic or universal adapter plates, this model is CNC-machined specifically for the SIG P320 slide, ensuring perfect fitment, proper alignment, and maximum durability under recoil. Calculated Kinetics has earned a strong reputation for producing high-quality, American-made optic mounting solutions trusted by competitive shooters, law enforcement, and serious firearm enthusiasts. This adapter plate offers a clean, professional installation that maintains the SIG P320’s excellent ergonomics while significantly improving target acquisition speed and accuracy.
