The Professional Program provenance sets this example apart. It was configured for law enforcement use and subsequently released as surplus to the civilian market, providing buyers with a ready-to-use package that includes an installed ROMEO-X PRO optic and duty-focused features.
The slide is stainless steel with a Nitron finish and a Pro-cut optics interface with a removable plate, plus forward and rear serrations for confident manipulation. A loaded chamber indicator is integrated, and the pistol retains XRAY3 Day/Night sights with a green front; the rear notch is integral to the mounted optic.
The XSeries full-size grip module is polymer with an extended beavertail and a high undercut trigger guard, complemented by SIG medallions. The flat-faced XSeries trigger provides a consistent striker-fired pull, and a three-slot M1913 dust-cover rail supports weapon-mounted accessories.
At its core is the serialized modular FCU design, allowing the well-known P320 adaptability. Chambered in 9mm Luger with a 4.7 in barrel, this pistol carries a 17+1 capacity and ships with three 17-round factory magazines. Proof marks indicate Newington, NH, USA manufacture.
