Experience enhanced versatility with our factory-installed Romeo-X Pro optic on the P320 RXP X series stainless steel slide assembly. This innovative design allows the optic to sit remarkably low on the slide, ensuring seamless co-witnessing with standard height iron sights when the optic is not in use. Enjoy a consistent and familiar sight picture, eliminating the need for suppressor height sights. This slide assembly is a factory replacement compatible with Compact size (X series and non-X series) grip modules, designed to accommodate our 3.6 inches barrel (not included).
