The Sig Sauer P320 Pro-Cut Slide Assembly brings tactical upgrades to your modular P320 without sacrificing the clean lines that make this platform so popular. Starting with genuine Sig Sauer factory engineering, this slide comes precision-machined from stainless steel and finished in a PVD coyote color that pairs function with aesthetics. It's built to drop right onto your existing grip module with zero gunsmithing required.
What sets this slide apart is the thoughtful engineering behind those stylized relief cuts across the front. They do triple duty: reducing overall weight for snappier cycling, improving cooling during extended range sessions, and giving the slide a distinctive appearance that stands out without looking gimmicky. The cut-out design doesn't compromise structural integrity at all. You also get aggressive front and rear serrations for reliable manipulation, whether you're running the gun hot or dealing with wet conditions.
This slide is milled for the R2 footprint, meaning it accepts Romeo1 Pro, Romeo2, Delta Point Pro, and RMR optics (RMR requires a sealing plate). The cut comes with a removable optics plate and top-accessible mounting screws that make installation and zeroing straightforward. What's really practical here is that it ships with XRAY3 day/night suppressor-height sights already installed. Those suppressor-height irons sit tall enough to cowitness your red dot, giving you a legitimate backup aiming solution if your optic goes down. They perform well in low light too, thanks to the night sight tritium inserts.
The slide is fully assembled and drop-in ready. It includes the striker and extractor pre-installed, so you're not buying a stripped upper and dealing with additional parts. This is for 9mm use with 3.9-inch barrels, whether you run a standard non-threaded barrel or step up to a 4.6-inch threaded option. It works with P320 Compact and X-Compact grip modules. The factory Sig engineering means zero fitment headaches, and using this OEM slide doesn't void your P320 warranty.
Yes, this 3.9-inch Pro-Cut slide fits P320 Compact and X-Compact grip modules. It's drop-in compatible with both standard and X-Series configurations. Just make sure your barrel length matches—this slide uses 3.9-inch non-threaded barrels or 4.6-inch threaded barrels. No fitting or gunsmithing is required.
Absolutely. The slide ships with XRAY3 suppressor-height iron sights already installed, so you can run it without any optic. If you later decide to add a red dot, the sights will cowitness with most footprints, giving you a proven backup aiming system.
This slide is milled for the R2 footprint and accepts Romeo1 Pro, Romeo2, Delta Point Pro, and Trijicon RMR optics. RMR mounting requires a sealing plate for proper recoil transfer. The slide ships with a removable optics plate and comes with top-accessible mounting screws.
The slide itself is complete and ready to drop onto your grip module. However, you'll need your own 9mm barrel (3.9-inch non-threaded or 4.6-inch threaded) and recoil spring assembly, which are sold separately. This is just the slide assembly with sights and internal components pre-installed.
