SIG Sauer P320 Pro Full-Size 9mm Luger – Agency-Vault Law-Enforcement Allocation, 4.7" Barrel, 17+1, XRAY3 Sights
This P320 Pro Full-Size comes from SIG Sauer’s restricted Agency-Vault production run for U.S. law-enforcement contracts, making civilian examples uncommon. It pairs the P320’s modular fire-control unit with the X-Series grip, flat-faced trigger, and factory-installed XRAY3 tritium sights, delivering duty-grade reliability in an as-new package.
Condition
Overall Condition: As-new condition with no signs of prior handling beyond factory inspection.
Bore Condition: Excellent – clean, mirror finish with sharp lands and grooves.
Specific Condition Notes: Shows only factory test firing, with no visible wear on slide, frame, or internals.
What’s Included
- SIG Sauer gray polymer hard case
- Three 17-round factory SIG Sauer steel magazines
The Pro-series X-Full grip module features aggressive stippling, an extended beavertail, and a deep under-cut trigger guard for secure control during rapid strings.
The stainless-steel slide wears SIG’s durable Nitron matte-black finish and is machined with forward and rear cocking serrations for confident manipulation in any condition.
A skeletonized, flat-faced trigger breaks at approximately 5.5 lb, providing a consistent, striker-fired pull that supports accurate follow-up shots.
The fully modular fire-control unit allows users to convert caliber or frame size without tools, preserving the serialized component while adapting the pistol to mission requirements.
Factory SIG XRAY3 day/night sights offer a high-visibility green tritium front ring and serrated tritium rear for fast, precise sight alignment in all lighting.
