Configured as the XFULL size in the XSeries lineup, this P320 PRO variant combines a striker-fired system with a flat-faced trigger and a reversible magazine release for straightforward, duty-ready controls. The polymer grip module and Nitron-finished slide provide a durable, blacked-out presentation. XRAY3 day/night sights are included, with a green front night sight and a rear sight located on the optics plate when the optic is installed.
The ROMEO-X PRO red dot is installed on the slide’s PRO/SIG-LOC footprint and offers a selectable dot or circle-dot reticle. The slide includes deep front and rear serrations for confident manipulation, and the 4.7 in non-threaded carbon-steel barrel supports the full-size balance this model is known for.
This pistol was issued for law enforcement personnel and later made available as surplus to the civilian market. The included case label shows the model code W320F-9-BXR3-PRO-RXX with a date of 23-OCT-2024, aligning this example with recent production and the PRO configuration.
Capacity is 17+1 in 9mm Luger, and this package includes three factory steel magazines. The frame integrates a MIL-STD-1913 three-slot accessory rail, and the modular P320 FCU architecture underpins the design. Overall length is approximately 8.2 in, and weight is about 29.6 oz with magazine.
