SIG Sauer P320 X-Series XFull Professional 9mm – Agency Vault, Optic-Ready, XRAY3 Sights, 17+1
This limited-release P320 XFull Professional comes straight from SIG Sauer’s Agency Vault law-enforcement allocation, making civilian examples uncommon. Built on the modular P320 chassis, it blends duty-grade strength with X-Series ergonomics, a factory-installed flat trigger, and an optic-ready R2 slide that accepts SIG Romeo2, Romeo1 PRO, and Leupold DeltaPoint PRO reflex sights without adapter plates.

The Professional-series P320 starts with a stainless-steel fire-control unit housed in a full-size polymer X-Series grip module that features an extended beavertail, deep trigger-guard undercut, and molded stippling for solid purchase during rapid strings.
Its carbon-steel 4.7-inch barrel and matte-black Nitron slide deliver duty-ready durability. Front and rear serrations enable confident press-checks, while the optic-cut slide cap carries a serrated square-notch rear sight that pairs with a SIG XRAY3 tritium front for 24-hour visibility.
The flat-faced, striker-fired trigger averages a crisp 6-pound break, promoting a straight-to-rear pull that many shooters find enhances control. Combined with SIG’s five-slot MIL-STD-1913 rail, the pistol is ready for lights and other mission-essential accessories.
Because this variant was produced for police and government contracts, civilian availability is limited to aftermarket channels—adding collectability to its proven performance.
