Sig Sauer P365XL 9mm 3.7" Bbl Micro XRAY3 Sigloc Optic Ready Blk Slide Assemby SLIDE-365XL-9-BLK

The SIG Sauer P365XL 3.7″ Slide Assembly is a factory OEM optics‑ready upper built to give P365 family pistols an extended‑slide look with full micro‑optic capability. Finished in black Nitride and machined from stainless steel, the 3.7″ assembly ships with XRAY3 day/night sights and a removable SIG‑LOC micro‑optic plate (top‑accessible) to accept popular compact dots (ROMEO‑X/ROMEOZERO, RMSc/Shield RMS‑C footprints). Designed to fit P365X, P365XL and P365‑XMACRO grip modules, the slide includes all internal slide parts but is sold as the slide assembly only — barrels and recoil assemblies are purchased separately — making it an easy, factory‑backed option for building or refreshing a micro‑compact, optics‑ready P365 variant.
