The P320-XFULL pairs a 4.7 in carbon steel barrel with a stainless-steel slide finished in black Nitron, offering front and rear serrations for confident manipulation. Overall length is 8.2 in, width 1.3 in, height 5.5 in, and weight 29.6 oz.
Its R2/PRO optics-ready slide uses the PRO footprint for direct mounting of compatible optics (ROMEO1PRO/DeltaPoint Pro). The rear sight is integrated into the removable optics cover plate, and the factory SIG XRAY3 day/night sights provide a bright green-dot front with a square-notch rear.
The X-Series grip module features molded texture, an extended beavertail, and a high undercut for a solid, repeatable purchase. The flat-faced X-Series trigger delivers a consistent striker-fired pull. An M1913 accessory rail with three slots supports lights or lasers.
Built around Sig's modular, serialized FCU visible through the grip window, this variant has no external manual safety. Capacity is 17+1 per factory specification.
