The Sig Sauer P320 ROMEO-X Pro Slide (brand part number 8901534) pairs the low-profile ROMEO-X Pro reflex optic with a Two Port Slide Integrated Expansion Chamber, a recoil-mitigation feature built into the slide itself. Machined by Sig Sauer in a black finish for the 9mm Luger P320, this slide keeps the extremely low overall height of the fast-to-find ROMEO-X Pro sight while still co-witnessing with the included standard-height iron sights, eliminating the need for bulky, high-over-bore suppressor sights. The integrated expansion chamber vents gas to reduce felt recoil, helping shooters get back on target faster for follow-up shots.

Frequently Asked Questions

What does the expansion chamber do? It vents gas through two ports machined into the slide to help reduce felt recoil and speed up follow-up shots.

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