Sig Sauer P320 XTEN Pistol rounds out the XSeries with a 10mm Auto model. The 5” slide and barrel offer unparalleled accuracy and comfort without sacrificing the ability to carry concealed. The grip module is compatible with the removable magwell and grip weight and is designed with an extended beavertail and deep undercut for a high grip and better recoil control.  The XRay3 day/night sights offer high visibility in all lighting conditions, and the rear sight plate assembly allows the direct mounting of the new Romeo2 optic, as well as the popular Trijicon RMR.  The LCI flag allows visual and tactile confirmation of a loaded chamber with ease.
