The XFULL Pro format delivers a 4.7 in carbon steel barrel, full-size XSeries grip module, and 17+1 capacity in a striker-fired system. The flat-faced trigger and XSeries ergonomics provide a straight, consistent press within a full-size footprint.
The ROMEO-X PRO is factory mounted and aligned to co-witness with the SIG XRAY3 day/night irons. The XRAY3 luminous green front dot and rear notch offer a clear reference should you prefer or need to run irons alone.
The Pro-cut stainless slide wears a Nitron finish and features front and rear serrations plus an optics cut, complementing the pistol’s duty-ready configuration. The XSeries full-size polymer grip module includes an extended beavertail and a high undercut.
The modular FCU design supports straightforward configuration changes, while the M1913 accessory rail on the dust cover accepts compatible lights or accessories. This pistol was issued for Law Enforcement personnel, and this surplus model has been made available to the civilian market. The case label (W320F-9-BXR3-PRO-RXX) matches the pistol’s serial number on file.
