Description
Upgrade your P320™ with a perfect balance of added weight and features.
The P320™ XFIVE TXG 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 12-lb. spring and (2) 17-rd Magazines included.
All of these new features, coupled with the removable magwell and 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.
Note: Not recommended for use with P320™ pistols chambered in .45ACP and 10mm.
