Issued for law enforcement service and later released as surplus to the civilian market, this Professional Series configuration reflects the LE-channel package of the P320. It retains the full-size 4.7-inch format, ships with three 17-round magazines, and remains in excellent overall condition.
The Nitron-finished slide includes front and rear cocking serrations and a beveled Pro-style nose. Its PRO optics cut follows the DeltaPoint Pro pattern and is paired here with the factory-mounted SIG Sauer ROMEO-X Pro. The optic integrates the rear notch, working with the X-RAY3 day/night front sight, and its low deck height enables a standard-height co-witness.
Built on the X-Series full-size polymer grip module, this striker-fired P320 uses a flat trigger and has no external manual safety. The modular stainless steel fire control unit is removable, and the serial on the FCU matches the case label. A full-length M1913 accessory rail runs along the dust cover for mounting compatible accessories.
This RX (ROMEO-X Pro) variant is finished in black and made in the USA. It carries the Professional Series features buyers expect and is identified by mfg part number W320F-9-BXR3-PRO-RXX. MSRP is listed at 999.99.
