Sig Sauer
The Sig Sauer P365X slide assembly in Coyote Tan with Nitride finish is a complete, factory-built replacement slide designed for shooters who want a modern micro-optics platform without replacing their entire pistol. Built on stainless steel and finished in durable Coyote PVD, this slide comes fully loaded with internal parts and XRAY3 Day/Night sights, so you're ready to mount glass or run irons straight out of the box. Whether you're upgrading an existing P365 or building a second configuration, this optics-ready slide transforms your pistol into a red-dot-ready platform that fits your existing holsters and handling habits.
The micro-optics cut accommodates compact sight footprints including Sig's own ROMEO ZERO/ROMEO ZERO ELITE, as well as popular third-party options like the RMSc and 507K. The removable sight plate lets you swap between optics or return to iron sights without tools or permanent modification. XRAY3 Day/Night sights come installed, giving you a reliable backup sight system that works in bright sun or low light before you ever add a red dot.
Installation is straightforward: pair this slide with a 3.1" non-ported barrel and a P365X recoil spring assembly, and you'll have a complete, functioning slide unit. The compact design and Coyote Tan finish blend into most carry or duty configurations. This is genuine Sig factory hardware, not an aftermarket clone—built to Sig's tolerances and reliability standard.
