SIG Sauer P320 X-Series Pro Full-Size 9mm 4.7" LE Agency Vault Pistol – 3 x 17-rd Mags, XRAY3 Night Sights
This P320 X-Series Pro comes directly from SIG Sauer’s Law Enforcement Agency Vault allocation, a channel usually reserved for police and government contracts. Civilians rarely see these factory-fresh pistols, making this example a standout opportunity. The full-size frame, flat-faced trigger, and XRAY3 tritium sights combine with an optic-ready Nitron slide for a duty-grade package that is ready for serious use.

Built on SIG’s modular P320 platform, the X-Series Pro pairs a full-size grip module with a 4.7-inch stainless steel barrel, giving shooters maximum sight radius and recoil control. The polymer frame features aggressive stippling and an integral Picatinny rail for weapon-mounted lights or accessories.
The flat-faced X-Series trigger delivers a consistent, crisp break that many shooters prefer for fast, accurate follow-up shots. Forward and rear slide serrations offer positive traction for press checks and manipulations, while the Nitron finish provides long-term corrosion resistance.
SIG’s XRAY3 night sights place a high-visibility green ring front blade between two tritium rear dots for a clear sight picture in any lighting. The slide is optic-ready, allowing direct mounting of compatible micro red-dots without adapter plates.
Chambered in 9mm Luger, the pistol ships with three 17-round magazines, giving you 51 rounds on tap right out of the case. Produced in the USA, this Agency Vault Pro model carries the factory part number W320F-9-BXR3-PRO.
