Sig Sauer P320 Compact X-Carry 9mm Luger 3.9" Slide Assembly w/ ROMEO-X PRO Optic - Coyote Brown

The Sig Sauer P320 Compact X-Carry Slide Assembly with factory-mounted ROMEO-X PRO reflex optic gives any 9mm Luger P320 Carry or Compact frame a turnkey optics-ready upgrade. Machined and finished in Coyote Brown, the slide ships with co-witnessed XRAY3 day/night sights so the pistol remains usable even when the optic is depowered. The factory-installed ROMEO-X PRO sits low enough that the included iron sights stay visible through the lower window of the glass, eliminating the need for tall suppressor-height backups.

Chambered for 9mm Luger and cut for a 3.9 in barrel, this slide assembly is engineered to drop onto P320 Compact and P320 Carry frames, bringing the X-Carry line's feature set to existing builds. The ROMEO-X PRO reflex optic pairs a CNC-machined 7075 aluminum housing with a patent-pending beryllium copper flexure arm and a distortion-free aspherical lens in an open-emitter design. Inspired by the MIL-SPEC ROMEO-M17, the optic brings battle-proven architecture to a compact, duty-grade red dot engineered to live on a P320 slide.

Whether the application is self-defense, target shooting, concealed carry, everyday carry (EDC), competition shooting, or law enforcement use, this Compact X-Carry slide assembly delivers a modern, slide-mounted aiming solution right out of the box.
