The Sig Sauer P320 357 Sig TXG Grip Module features tungsten-infused polymer constructed through a patent-pending molding process that delivers the weight characteristics of steel combined with the flex properties of polymer. Transfer your P320 Fire Control Unit into the TXG to achieve 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 newer style magazines bearing the circular SIG SAUER logo and square locking tab on the basepad. Magazines marked SIG SAUER with circular locking tabs require modification to fit properly. Newer style basepads and locking plates are available separately.
