SIG Sauer P320 X-Series Carry Pro “Agency Vault” 9mm — Limited-Release LE Overrun, 3.9" Barrel, 17+1 Capacity
Built for duty and released in scarce numbers, this “Agency Vault” P320 X-Series Carry Pro is a limited-edition overrun from SIG Sauer’s law-enforcement production line. It pairs a compact-length Nitron-finished slide with a full-height XCarry grip module, giving you 17-round capacity in a shorter, highly controllable package. Factory tritium day/night sights, a PRO-footprint optic cut, and a flat-faced trigger round out a modular striker-fired pistol that shares its core fire-control unit with the U.S. military’s M17/M18 family.

This rare Carry Pro variant originated from SIG’s Law Enforcement allocation and reached the civilian market only through aftermarket channels. Each pistol retains the modular, serialized stainless-steel fire-control unit that legally constitutes the firearm, allowing easy caliber or grip module changes without an FFL transfer.
The 3.9-inch stainless barrel rides in a Nitron black slide cut with front and rear cocking serrations and a removable cover plate for the PRO optic footprint. Mount a SIG Romeo1 Pro or Leupold DeltaPoint Pro directly—no milling required.
The XCarry polymer grip module delivers enhanced ergonomics: extended beavertail, deep undercut, and X-Series stippling for a locked-in feel, plus a subtle flared mag-well lip to speed reloads. A flat-faced trigger provides a straight-back press and consistent break.
Standard green-ring tritium front and two-dot tritium rear sights offer 24-hour visibility. An integrated Picatinny accessory rail supports lights or lasers, making this pistol equally suited for duty, defense, or range roles.
