The SIG Sauer P320 Pro-Cut Slide Assembly is a factory, optics-ready replacement slide built to fit P320 Compact (non-X-Series) and Full-size grip modules, both X-Series and non-X-Series, from Sig Sauer (brand part no. 8900949). Front and rear slide serrations give a secure purchase for racking and press-checks, and it comes equipped with SIG’s X-Ray3 sight set. Because it’s a genuine SIG Sauer factory part, it drops onto a compatible P320 frame with correct fit and function. It’s a straightforward way to add a red-dot-ready slide to an existing P320 without buying a second pistol.
