The Sig Sauer 8900274 P320 Grip Module X-Series TXG delivers a pioneering balance of weight and versatility, using tungsten-infused polymer molded through a patent-pending process to achieve the weight of steel with the flex and impact resistance of polymer, resulting in one of the flattest, softest shooting pistols on the range when the P320 Fire Control Unit is installed into the TXG grip module. This large grip module is designed for 9mm Luger, 40 S&W, and 357 SIG calibers and fits the full-size Sig P320 with its 4.70" frame, providing enhanced control and comfort during rapid fire or precision shooting. While it trades some traditional features for streamlined performance, note that the extended magwell and internal weight are not included, and the X-Series grip modules require newer style magazines with the circular SIG SAUER logo and square locking tab on the basepad, with newer basepads and locking plates available separately. Elevate handling, reduce recoil impulse, and improve shot-to-shot consistency with the TXG grip module in your P320 setup for a refined, tournament-ready, all-day shooting experience.
