The XSeries XFULL Pro configuration delivers a Pro-cut slide with forward and rear cocking serrations, a Nitron black finish, and an optic cut paired here with SIG's factory-installed ROMEO-X. The ROMEO-X features a low deck height intended to co-witness with standard-height irons and draws lineage from the ROMEO-M17, giving a clean, fast sight picture with a red reticle.
SIG's X-RAY3 day/night sights include a tritium front sight with a green outline for visibility in varied lighting. Together with the ROMEO-X, these sights provide immediate alignment and redundancy without adding bulk.
The full-size XSeries polymer grip module, flat-faced trigger, and striker-fired action offer a consistent trigger press and confident control. The integral three-slot 1913 accessory rail supports common duty lights and accessories, and the 4.7" barrel balances sight radius and handling.
This pistol was issued for Law Enforcement personnel; this surplus model has been made available to the civilian market. The Professional Program "W" prefix is reflected in the SKU, and the case label is dated October 23, 2024. The frame is marked NEWINGTON, NH, USA.
