SIG Sauer P320 XFULL Pro-Cut 9mm – Law-Enforcement Vault Allocation, 4.7" Barrel, 17+1, Optics-Ready
The P320 XFULL Pro-Cut is a factory-enhanced, striker-fired 9mm built for duty performance and collector appeal. Produced in SIG Sauer’s Agency Vault for law-enforcement contracts, this limited-allocation model adds a Pro-Cut slide that accepts ROMEO1 PRO, ROMEO2, and DeltaPoint PRO footprints, plus X-Series upgrades rarely seen on civilian P320s. It ships with three 17-round magazines and retains the modular fire-control unit adopted by the U.S. military’s M17/M18, making this example both highly capable and exceptionally hard to find outside official channels.

This XFULL Pro-Cut comes directly from SIG’s Law-Enforcement Vault allocation, a channel normally reserved for police and government agencies. Availability to civilian buyers is extremely limited, adding significant collectibility to an already respected duty handgun.
The Pro-Cut slide features extensive lightening windows, forward and rear cocking serrations, and a factory optics cut that mounts ROMEO1 PRO, ROMEO2, or DeltaPoint PRO red dots without plates. Matte black Nitron finish resists corrosion while matching the X-Series aesthetic.
Inside, a 4.7-inch stainless-steel barrel and stainless slide work with the modular, serialized fire-control unit. This design lets owners swap calibers, slides, and grip modules while keeping one serial number—ideal for shooters who value adaptability.
The flat-faced, skeletonized trigger promotes a straight-back press and short reset, while the full-size X-Series polymer grip module offers an extended beavertail, enhanced undercut, and aggressive texturing for confident control.
SIG X-RAY 3 day/night tritium sights provide a bright green front dot flanked by two rear dots for clear sight pictures in any light. A full Picatinny rail allows easy attachment of weapon-mounted lights or accessories to round out this capable, ready-to-work pistol.
