Love the new slide with Romeo X Pro optic. Slid it onto my M17 and went to the range. Shot some of my best groups. So, what about the best kept secret? The Romeo X Pro optic cost is about $450+- dollars, a bare P320 slide cost is about $350 +-. ...

Product Info for SIG SAUER Pro P320 9mm Romeo X Pro XRAY3 Sights Barrel Assembly

Enjoy using a slide-mounted reflex sight without needing suppressor height iron sights. The factory-installed ROMEO-X PRO optic sits incredibly low to the slide so you can still use standard height iron sights when the optic is not in use, giving you a consistent, familiar sight pictureimage
