The Sig Sauer P320 X-Series Medium Grip Module Assembly features a TXG grip module constructed from tungsten-infused polymer molded using a patent-pending process. This manufacturing method delivers the weight characteristics of steel combined with the flex properties of polymer. Transfer your P320 Fire Control Unit into the TXG for one of the flattest, softest shooting pistols available.
Please note: This grip module does not include the extended magwell and internal weight. The X-Series Grip Modules are compatible only with new style magazines bearing the circular SIG SAUER logo and square locking tab on the basepad bottom. Magazines marked SIG SAUER with circular locking tabs require modification to fit properly. Newer style basepads and locking plates are available separately.
