SIG Sauer P320 X-Series Pro 9mm 4.7" — Agency Vault Law-Enforcement Allocation, Optic-Ready, XRAY3 Sights, 17+1
This full-size P320 X-Series Pro comes from SIG Sauer’s limited Agency Vault run for police and government contracts, making civilian examples scarce. It pairs the P320’s modular stainless-steel fire-control unit with an optic-ready Nitron slide, XRAY3 tritium day/night sights, and a flat-faced skeletonized trigger. With its factory 17-round magazines and barely-used condition, this pistol offers collectors and shooters a chance to own a law-enforcement–spec P320 that rarely appears on the commercial market.

The Agency Vault designation signifies a law-enforcement allocation not originally offered to the general public, adding collectability to this X-Series Pro. Built around SIG’s modular fire-control unit, the pistol allows caliber or grip module changes without tools while maintaining a stainless-steel chassis for strength.
The 4.7-inch stainless barrel teams with a black Nitron slide that features forward and rear cocking serrations plus a factory-milled optic cut under the removable rear-sight plate. XRAY3 tritium sights deliver a bright green front dot and serrated rear blades for fast day or night targeting.
SIG’s X-Series polymer grip module (medium size) offers an undercut trigger guard, high beavertail, and aggressive texturing for a secure hold. The flat-faced, skeletonized trigger promotes a straight-back pull, while the reversible magazine release accommodates left- or right-hand shooters.
Capacity sits at 17+1 rounds of 9mm Luger, and the 6.6-inch sight radius maximizes accuracy potential. With three factory magazines and its original case, this lightly-used, law-enforcement–spec P320 is ready for duty or range use right out of the box.
