If you've got a P320 and want to run a Trijicon RMR or SRO red dot, this is the plate that makes it work. Sig Sauer engineered this adapter specifically for their P320 line, and it's the straightforward way to get your optic mounted without any guesswork.
The kit includes everything you need right out of the box. You get the precision-machined mounting plate, the sealing plate that covers the cutout underneath your optic, and the hardware to secure it all together. Installation uses your P320's existing slide mounting points, so you're not drilling new holes or doing anything permanent. A 2mm hex wrench handles the 6-40 mounting screws, and the whole job takes maybe fifteen minutes if you're moving slowly.
The sealing plate piece is what separates this from just bolting an optic down. It seals off the space between your slide and the optic's footprint, which matters because it keeps moisture and debris away from the optic's battery compartment and electronics. The hard-anodized finish on the mounting plate itself resists corrosion and wear from regular handling and shooting. Quality steel construction means it won't flex or shift under recoil, so your zero stays put.
This adapter is built for P320 slides that are actually milled for RMR mounting. If your slide has the X-Series cut or the Pro-Cut with RMR footprint capability, you're good. Standard P320 slides without that specific milling won't work with this plate, so verify your slide's optics cut before ordering. Once it's on, you can use it with any Trijicon RMR or SRO optic that shares that footprint.
Whether you're building a competition gun, duty setup, or just want faster target acquisition on your carry pistol, this plate gives you a rock-solid foundation for your optic choice.
No, this adapter plate is specifically designed for P320 slides that are milled for RMR footprint mounting, including P320 X-Series and P320 Pro-Cut variants. Standard P320 slides without the factory RMR-cut optics milling won't be compatible. You'll need to verify your slide's optics cut before purchasing.
This plate is designed specifically for Trijicon RMR and SRO red dot sights that use the RMR footprint. Other red dots with different mounting footprints will not work with this adapter. Check your optic's footprint specification before ordering.
The sealing plate covers the gap between your slide's optics cutout and your red dot's footprint. This prevents moisture, dirt, and debris from getting into the space underneath your optic where the battery and electronics are located, protecting those components from water damage and contamination.
You'll need a 2mm hex wrench or allen key to tighten the included 6-40 mounting screws. The adapter uses your P320's existing factory mounting points, so no drilling or permanent modifications are required. Installation typically takes 10-15 minutes.
