The P320-XTEN brings the P320's modular architecture to the 10mm Auto, using Sig's removable FCU for straightforward maintenance and configuration. The full-size X-Series grip module offers a stable purchase for managing full-power 10mm loads, paired with a flat-faced trigger for a consistent, straight-back press.
The Nitron-finished slide features front and rear serrations, an R2 optics cut with cover plate, and an external extractor. Factory XRAY3 steel day/night 3-dot sights are installed, with a green-dot tritium front (marked TG-H3) and a square-notch steel rear, delivering a 6.8 inch sight radius.
A 5 inch bull barrel anchors the system, and a five-slot 1913 accessory rail on the dust cover supports lights or lasers. Capacity is 15+1 using the included steel double-stack magazines.
