The Professional Program configuration (SKU W320F-9-BXR3-PRO-RXX) pairs the XFULL 9mm platform with a ROMEO-X Pro installed at the factory. The X-RAY3 day/night iron sights co-witness with the optic due to its low deck height, providing a clear sight picture through the window while retaining a conventional sight reference.
This XSeries full-size model uses the modular P320 FCU architecture, allowing the stainless steel fire control unit to sit in an XSeries grip module with an extended beavertail and deep undercut. It is a striker-fired, semi-automatic 9mm with a flat-faced trigger, 4.7in barrel, and a 17+1 capacity in the XFULL configuration.
Controls are set up for duty-friendly handling: ambidextrous slide catch levers, a reversible magazine release, and a 3-slot M1913 accessory rail. The slide includes front and rear serrations, an optics cut, and an external extractor, all finished in Nitron black.
Provenance and packaging details are documented: the case label is dated 28-OCT-2024, the serial number on the FCU matches the case label, and the pistol is marked Newington, NH, USA. This pistol was issued for Law Enforcement personnel and is now offered to the civilian market as surplus.
