Sig Sauer
The Sig Sauer Slide Pro-Cut P320 Subcompact 3.6" 9mm optic-ready slide gives you a factory-quality upgrade path for your P320 build or repair. This is a slide-only component—you'll need to pair it with a compatible barrel and recoil assembly—but it arrives pre-finished and ready to accept a modern red dot. Whether you're modernizing a carry gun, assembling a competition build, or replacing a worn slide, this machined stainless steel assembly delivers Sig's Pro-Cut styling and proven reliability in the compact footprint that works for shooters who prioritize concealability without sacrificing shootability.
The slide is milled optic-ready and accepts industry-standard sight footprints: ROMEO1-Pro, ROMEO2, Delta Point Pro, and RMR (with sealing plate). The removable optics plate design means you can access screws from the top, making mounting and maintenance straightforward in the field or at the bench. X-RAY3 Day/Night suppressor-height sights come installed, so you can run a red dot co-witnessed or go optics-only. The Coyote Nitron finish pairs durability with a modern aesthetic that's at home on the range or in a duty belt.
This is the slide component only—barrel, recoil spring assembly, and lower receiver are sold separately. The slide is chambered for 9mm Luger and will not function with .40 S&W, .357 SIG, or .45 ACP barrels. Sig backs this component under its standard warranty, and installation doesn't void your firearm's coverage. If you're a P320 subcompact or X-Compact owner looking to modernize your iron sight setup or add a red dot with a clean, purposeful aesthetic, this is the piece that makes it happen.
