Delight in the versatility of our P320 RXP X series stainless steel slide assembly featuring the factory-installed Romeo-X PRO optic. This innovative setup allows the optic to sit exceptionally low on the slide, enabling seamless co-witnessing with standard height iron sights when the optic is not in use. Enjoy a consistent and familiar sight picture without the need for suppressor height sights. This slide assembly is a factory replacement compatible with Full, Carry and Compact size (X series and non-X series) grip modules, designed to accommodate our 4.7 inches barrel (not included).
