The XTEN XSeries is the full-size 10mm variant of the P320 platform, built around Sig Sauer’s modular fire control unit for easy configuration. This example is a 2024 production pistol with a stainless steel receiver, polymer XSeries grip module, and a capacity of 15+1.
A 5-inch bull-profile steel barrel anchors the setup, working with the striker-fired action and a flat-faced trigger to deliver a consistent trigger press. The aggressive-texture XSeries grip module includes an extended beavertail and high undercut for a secure, high grip.
The Nitron-finished slide is machined with front and rear serrations and is optics-ready with a removable cover plate. Ambidextrous slide-catch levers and a multiple-slot accessory rail support practical setup and operation.
Factory tritium night sights include a front sight with a green ring and TG-H3 marking, paired with a black rear notch containing tritium vials. Two steel magazines are included, each with witness holes, and the pistol carries Sig’s XTEN XSeries part number 320X5-10-BXR3-R2.
