The P320-XTEN stands out as the platform's inaugural 10mm Auto release, designed around the larger X-Series grip module sized for the 10mm/.45 frame architecture. It offers a 15+1 capacity and approximately 33 oz weight with magazine, providing a strong balance for the cartridge.
Its 5 inch bull barrel works with a striker-fired, short-recoil, locked-breech action. The flat-faced trigger promotes a consistent, straight press, while the left-side magazine release and ambidextrous slide-catch levers support practical operation.
The optics-ready slide is finished in matte black and ships with steel day/night sights. A high-visibility green dot front pairs with a square-notch rear for a clear sight picture out of the box.
The polymer X-Series grip module features textured grip panels for secure handling. A 1913 Picatinny accessory rail on the dust cover accommodates compatible lights or accessories. This pistol is made in the USA.
