The installed Wilson Combat compact-size polymer grip module distinguishes this P320 XCompact with Wilson Combat and Berryville, AR, USA molded markings. This factory-compatible module delivers the Wilson Combat fit and feel on SIG's modular P320 platform while maintaining compact dimensions.
The XSeries feature set includes a flat-face trigger, ambidextrous slide catch levers, and a reversible magazine release. The striker-fired action and compact 3.6-inch steel barrel are paired with a 15+1 capacity, offering a balanced carry and range configuration.
The slide is optics-ready with an optic cut and exposed mounting holes, and it incorporates front and rear cocking serrations for confident manipulation. An integral three-slot accessory rail on the dust cover supports common lights or accessories.
Sight alignment is fast and clear via steel 3-dot sights, featuring a front dot with a bright green ring and a rear square-notch with two small dots. The modular SIG P320 serialized FCU platform allows the core fire control unit to interface with compatible P320 components and grip modules.
