SIG Sauer P320 X-Series XCarry Pro 9mm 3.9" — Law-Enforcement Agency Vault, Optic-Cut Slide, 17+1
This P320 XCarry Pro comes straight from SIG Sauer’s Law-Enforcement Agency Vault allocation, making civilian examples uncommon. It combines the compact 3.9" slide with a full-size 17-round grip module, a flat X-Series trigger, and a factory PRO-cut Nitron slide ready for ROMEO1 PRO-footprint optics. With modular fire-control unit, night sights, and three 17-round magazines, it delivers duty-grade performance in an as-new package.

The pistol originates from SIG’s restricted “Agency Vault,” built for police and government contracts and rarely released to the commercial market. Its serialized fire-control unit allows easy caliber or grip conversions while preserving the original firearm classification.
The stainless-steel slide wears SIG’s Nitron finish and features aggressive forward and rear serrations plus a PRO optic cut with a cover plate for direct-mounting ROMEO1 PRO-footprint red dots.
A flat-faced, skeletonized X-Series trigger offers a clean, consistent break in the striker-fired action. Coupled with the XCarry grip module, it provides a high undercut, extended beavertail, and full-length accessory rail for improved control.
X-RAY3 tritium night sights give a bright green front dot and two-dot U-notch rear for fast sight acquisition in any light. The 3.9" stainless barrel balances carry comfort with duty accuracy, while the 17+1 capacity meets modern defensive standards.
