This is a complete factory slide assembly for the P320 platform, built out from the jump with an integrated ROMEO-X PRO reflex optic and ready to work right out of the box. The real advantage here is the optic height. The ROMEO-X PRO sits low enough on the slide that your standard XRAY3 day and night sights stay fully functional and can work alongside the red dot. You get your iron sights visible through the optic for true co-witness instead of being forced to buy suppressor-height sights or sacrifice your backup sight picture.
The slide itself is made from stainless steel with a coyote PVD finish that delivers solid durability in the field. Front and rear serrations are cut vertically, which gives you positive purchase for press checks and one-handed manipulations when you need them. The full-size 4.7-inch length balances accuracy and recoil control without being cumbersome to carry or handle. This assembly fits P320 Full-Size, Carry, and Compact grip modules across both X-Series and non-X-Series platforms, making it extremely flexible if you're building or upgrading your setup.
What sets this assembly apart is that you're not piecing things together. The ROMEO-X PRO comes factory-installed and properly zeroed from Sig Sauer. You avoid the guesswork and parts sourcing that comes with building a complete slide from scratch. The optic design keeps everything low and streamlined without bleeding into sight radius, and the factory mounting means confidence that it'll hold zero through hard use.
This assembly is designed for 9mm, .357 SIG, and .40 S&W fire control units. It will not work with .45 ACP FCUs. The barrel shown is not included, but this slide accommodates the standard P320 4.7-inch barrel. You'll need a compatible grip module to complete your build, which gives you the flexibility to customize the frame side however suits your needs.
No, the barrel is sold separately. This assembly is designed for the standard P320 4.7-inch barrel, which you'll need to source and install on your compatible grip module to complete the build.
Yes, that's one of the big advantages of this assembly. The ROMEO-X PRO is mounted low enough that your XRAY3 sights stay in the field of view and co-witness with the red dot, so you don't need suppressor-height sights.
This slide fits P320 Full-Size, Carry, and Compact grip modules across both X-Series and standard (non-X-Series) models. It's one of the flexible aspects of the P320 platform that lets you customize to your preferences.
The optic is removable if you ever want to swap it out. The slide includes a removable cover plate that comes off to access the optic mounting interface, giving you flexibility down the line if your setup needs change.
