The Sig Sauer 8900273 P320 Grip Module X-Series TXG (Small Grip Module) combines cutting-edge engineering with practical on-range performance, using a tungsten-infused polymer molded into a precision part to deliver the weight of steel with the flex of polymer. This TXG grip module is designed for the P320 platform in 9mm Luger, 40 S&W, and 357 SIG, and the included Fire Control Unit can be installed to create one of the flattest, softest shooting pistols on the range. The grips patent-pending construction yields stability and feel, while its compatibility with Magwell and Weight features offers versatility for tuned handling. Please note that the grip module does not include the extended magwell or internal weight, and the X-Series modules will fit only newer style magazines with the circular SIG SAUER logo and square locking tab on the basepad; magazines marked with circular locking tabs may require modification, with newer basepads and locking plates available separately. Ideal for shooters seeking a compact, high-performance frame with the extended control of a tungsten-infused polymer formulation, this Sig Sauer TXG grip module provides a refined balance between weight, solidity, and smooth recoil for precise, confident shooting.
