The heart of this pistol is SIG’s serialized, removable Fire Control Unit, giving the owner full access to the P320’s renowned modularity. Swap frames, slides, barrels, or calibers while keeping the same serialized component—an advantage unmatched in most striker-fired platforms.
The PRO-cut stainless steel slide features forward and rear serrations for confident manipulation and an integral optic cut that directly accepts the SIG ROMEO1PRO, Leupold DeltaPoint Pro, and other compatible footprints. Matte black Nitron finish resists corrosion and preserves a low-glare profile.
Enhanced duty sights come standard: XRAY3 tritium front with high-visibility green ring and a serrated square-notch tritium rear for 24-hour sight acquisition. A flat-faced, skeletonized trigger promotes a consistent, straight-back press, while the reversible magazine release supports left- or right-handed use.
The full-size polymer X-Series grip module provides an extended beavertail, aggressive grip texture, and an integrated accessory rail. Combined with the 4.7-inch stainless barrel, the platform balances controllability with carry practicality and feeds from durable 17-round steel magazines.
Originally allocated for sworn professionals, this XFULL PRO offers the same features trusted by agencies—now available to the civilian buyer in outstanding, near-factory condition.
