The Sig Sauer P320 9mm optic-ready slide is a factory replacement component built for shooters who want modern red-dot capability on a proven platform. This PRO-CUT slide assembly ships with XRAY3 suppressor-height day/night sights and arrives milled for optic mounting—compatible with ROMEO1 PRO, ROMEO2, Delta Point Pro, and RMR footprints (RMR requires a sealing plate). Whether you're upgrading a duty gun, building a competition rig, or setting up a concealed-carry backup with modern aiming, this slide gives you the option to run iron sights or add your preferred compact optic.
The slide is finished in PVD black on stainless steel, with stylized relief cuts that break up the profile and add a touch of character without sacrificing durability. The removable optics plate keeps mounting screws accessible from the top, making optic changes and adjustments straightforward. This is the slide component only—barrel and recoil spring assembly are not included, so you'll need to transfer existing parts or source compatible components separately.
Sig offers this slide in three different configurations to match your barrel choice: 3.6", 3.9", or 4.7" (non-threaded versions), as well as threaded variants at 4.3", 4.6", and 5.5" for shooters running suppressors or muzzle devices. Verify your barrel length before ordering to ensure proper fit. The slide is cut for 9mm only and will not work with .40 S&W, .357 SIG, or .45 ACP barrels.
