The Sig Sauer P320 Pro-Cut slide assembly (brand part no. 8900948) is a factory replacement sized for Sub-Compact and X-Compact P320 pistols, finished in PVD black with an optics-ready cut for a wide range of red dot footprints. Built to run standard 9mm 3.6-inch non-threaded or 4.3-inch threaded barrels, it accepts the ROMEO1-PRO, ROMEO2, Delta Point Pro, and RMR (with a sealing plate) footprint, giving Sub-Compact carry pistols the same optics flexibility as their full-size counterparts. XRAY3 Day/Night suppressor-height sights and a removable optics plate with top-accessible screws round out a slide built for fast, everyday-carry setups.
