The Sig Sauer P320 ROMEO-X Pro Slide (brand part number 8901569) is a factory 9mm Luger slide assembly finished in Coyote Brown, built by Sig Sauer around the ROMEO-X Pro reflex optic. The optic is factory-installed low in the slide, letting the included standard-height iron sights co-witness through the window instead of requiring bulky suppressor-height sights for a consistent, familiar sight picture. It ships as a complete, ready-to-install assembly for P320 owners who want a color-matched upgrade along with factory-installed red-dot capability.

Frequently Asked Questions

Do I need suppressor-height sights for this slide? No, the ROMEO-X Pro sits low enough that the included standard-height iron sights co-witness through the optic window.

Is a barrel included with this slide? No, this is a slide assembly only; a compatible P320 barrel is sold separately.
