The Sig Sauer P320 TXG Grip Module is an X-Series replacement grip module designed for full-size P320 pistols. It is molded from tungsten-infused polymer to provide additional mass while retaining polymer flexibility. Install your P320 Fire Control Unit into the TXG and pair it with an X5 or full-size slide assembly for reduced perceived recoil and a flatter shooting platform.
