The P320-XTEN pairs a 5-inch bull barrel with a striker-fired action and a flat-faced trigger for a consistent, straight-to-the-rear press. The full-size XSeries grip module features aggressive texture panels that provide a secure hold.
Its optics-ready stainless slide wears a Nitron black finish and includes front and rear cocking serrations plus a cover plate. The slide is factory marked XTEN and P320.
Sight setup consists of a tritium front dot with a green lamp (marked TG-H3) and a plain black square-notch rear. The 6.8-inch sight radius supports precise alignment, and capacity is 15+1 with the included steel magazines.
The modular P320 Fire Control Unit is visible through the grip window, and controls include an ambidextrous slide catch. A full-length 1913 Picatinny accessory rail on the dust cover provides mounting space for lights or other accessories.
The black polymer frame is marked NEWINGTON, NH, USA, and the pistol is made in the USA. Overall finish and features align with Sig Sauer’s XSeries configuration for the 10mm P320 platform.
