The Pro Full-Size configuration pairs a 4.7 in barrel with a full-length slide and grip module, delivering the P320's modular architecture around a serialized stainless steel fire control unit. The black polymer frame uses molded stipple panels for consistent purchase.
Factory SIG X-RAY3 tritium night sights are installed, with a green-ring tritium front, both dovetailed. The slide is optics-ready.
Controls are set up for duty-ready handling: an ambidextrous slide catch lever and a reversible magazine release, plus front and rear cocking serrations and an external extractor. The flat-faced trigger provides a straight press within the striker-fired system.
A 1913 accessory rail with four usable slots supports lights or lasers. Capacity is 17+1 with the included steel magazines. This model is made in the USA and identified by MFG part number W320F-9-BXR3-PRO-RXX.
