If you're modernizing your P320 or building a compact 9mm duty gun with red dot capability, the Sig Sauer P320 9mm optic-ready slide with XRAY3 sights delivers factory reliability paired with tactical versatility. This is the slide assembly only—the core component that transforms your P320 platform to accept modern miniature reflex sights while keeping your day-to-night sighting solution intact. The black PVD finish resists corrosion and wear, making it dependable whether you're training at the range, running duty rounds, or managing backup irons on a defensive carbine build.
Sig engineered this slide with the shooter in mind. The PRO-cut optic mounting system accepts ROMEO1 PRO and ROMEO2 red dots, plus Delta Point Pro and RMR footprints (RMR requires a sealing plate). XRAY3 suppressor-height tritium sights co-witness with most common optics, so you're never left blind if your red dot fails. Top-accessible screws on the removable optics plate make mount-and-swap work quick, and the stainless steel construction under that black finish won't let you down through thousands of rounds.
This is a slide assembly only—you'll pair it with your choice of 9mm barrel (threaded or non-threaded, depending on your setup) and recoil spring assembly. Sig makes it easy: you can use this with standard P320 Sub-Compact and XCompact frame sizes and a range of barrel lengths from 3.6\" to 5.5". Buying a pre-cut factory slide from Sig sidesteps the guesswork of aftermarket milling and keeps your warranty intact.
