"From the SIG Custom Works shop comes the SIG SAUER P320-XTEN Endure 10mm Semi-Auto Pistol, built for extreme conditions and demanding use. Chambered in the powerhouse 10mm cartridge, it features an enlarged beavertail, high-undercut trigger guard, and a low bore axis that helps direct recoil straight back into the meat of your hand a must when dealing with the raw power of 10mm. The slide features an optics cut that accepts the use of SIG ROMEO2 and Trijicon RMR-footprint optics, and comes topped with XRay3 day/night sights for effective targeting in all light conditions. The XTEN Endure comes with a 5"" bull barrel that provides enhanced accuracy along with the already-potent ballistic performance of the 10mm round. The X Flat trigger breaks clean at 90 and resets quickly. The slide is finished in Cerakote and features a unique laser-etched topographic pattern. Endure X grip module also features LXG laser stippling that provides maximum grip during wet conditions. Includes three 15-round magazines.
