SIG Sauer P320 XCarry Pro 9mm 3.9" Agency Vault LE Allocation, Nitron Optic-Ready, 17+1
Built for duty and seldom offered to the public, this P320 XCarry Pro comes directly from SIG Sauer’s Law-Enforcement Agency Vault program. It pairs the proven P320 modular fire-control unit with an XSeries flat trigger, factory Pro-Cut slide milled for direct-mount optics, and X-RAY3 day/night sights. The result is a full-size 9 mm pistol that delivers duty reliability, ready-out-of-the-box accuracy and true shootability in a package rarely released outside agency channels.
Condition
Overall Condition: As-new condition with no signs of prior handling beyond what’s typical from inspection (see photos).
Bore Condition: Excellent — clean, mirror finish with sharp lands and grooves.
Specific Condition Notes: The pistol appears to have seen only factory test-fire and minimal additional use.
What’s Included
- SIG Sauer lockable hard case (gray polymer)
- SIG Sauer P320 owner’s manual
- Orange polymer chamber safety flag
- Three 17-round SIG Sauer factory steel magazines (Made in Italy)
This XCarry Pro is part of the XSeries line, featuring a modular, serialized stainless steel fire-control unit that allows caliber or grip-frame conversions without an FFL transfer. The XSeries flat, skeletonized trigger breaks at a crisp 90° for a consistent, repeatable pull.
The 3.9" carbon steel barrel is nitride-treated for durability and corrosion resistance, while the Nitron-finished slide wears front and rear cocking serrations, lightening cuts, and a Pro-Cut optic pocket compatible with popular red-dot footprints—no adapter plate required.
Its XSeries polymer grip module includes an integrated mag-well flare for faster reloads and three-slot accessory rail for lights or lasers. SIG’s X-RAY3 tritium sights provide a high-visibility green front dot and serrated rear blades for a crisp sight picture in all lighting.
Originally produced for police and government contracts, Agency Vault pistols like this one reach civilian hands only through limited aftermarket releases, making them a desirable acquisition for shooters who want duty-grade configuration straight from the factory.
