Sig Sauer P320 X5 TXG Caliber X-Change Conversion Kit 9mm with Fiber Optic Sights and 17-Round Magazines

The Sig Sauer Caliber X-Change Kit is the ultimate upgrade kit for the serious shooter. Increase the weight of your pistol thanks to the innovative TXG tungsten-infused grip module. This is the first of its kind in the firearms industry with the weight of steel and the flex of polymer, reducing muzzle flip by up to 50%. The recoil system uses a solid steel guide rod and a 14lb 1911-style spring, with an additional 12lb spring and (2) 17rd Magazines included. All of these features coupled with the removable magwell & grip weight, ROMEO1PRO optic-ready slide, 5" Stainless Steel barrel, and Dawson Precision fiber optic adjustable sights catapults this cal-x kit ahead of the competition and sets a new standard. Not recommended for use with P320 pistols chambered in.45ACP and 10mm.
