SIG SAUERA(R) P320-XTEN 10mm Semi-automatic Pistol The new P320-XTEN takes all the modularity, durability, and accuracy of the XSeries platform-and elevates it to the power of 10. Now available in the potent 10mm chambering, the P320-XTEN comes standard with a 5" bull barrel, XRAY3 day/night sights, and an XSeries optic-ready slide with front and rear serrations. For those looking for even more precision, every P320-XTEN is optics ready and compatible with the SIG SAUER ROMEO2 or Trijicon RMR, both of which can withstand the recoil of the 10mm rounds. The X-Series grip module is exclusive to this line and features a deeper trigger guard undercut, a higher back strap and an extended beavertail to ensure a higher grip for better recoil management. Like all XSeries P320s, the XTEN has the straight trigger that breaks at 90Adeg for an even better feeling pull. It's a competition-ready Pistol out of the box-and it's also a standard 320, with all the modularity that entails. Modular frame assembly allows you to change calibers: 9mm, .357 SIG, .40 S&W, and .45 ACP (conversion kits sold separately) Modular frame assembly allows you to change grip sizes (extra grip modules sold separately) 5" bull barrel delivers superior accuracy Trigger is the same as the standard 320 mechanically, but is flat and breaks at 90Adeg for better feel XRAY3 day/night sights for targeting in all conditions Optics-ready slide accepts Romeo2 and Trijicon RMR red dots Undercut trigger and higher extended beavertail for higher grip and better control Includes (2) 15-rd. magazines Order today!
