The Sig Sauer P320 X-Series TXG Grip Module Assembly is a full-size, medium grip designed to transform how your P320 performs on the range and in the field. Built with a patent-pending tungsten-infused polymer formula, this grip module delivers the heft and stability of steel combined with the recoil absorption of modern polymer—a rare combination that shooters notice immediately. Whether you're running 9mm, .357 Sig, or .40 S&W, the TXG grip provides a substantial upgrade to your P320's handling characteristics, helping you shoot flatter and softer with less muzzle rise and fatigue over extended shooting sessions.
This assembly comes factory-equipped with the extended magwell and integrated internal weight, bringing the total module weight to 16.6 ounces. That purposeful heft, concentrated low in the grip, works with the P320's modular design to improve balance and reduce felt recoil. The gray finish is clean and durable, matching the modern aesthetic of the X-Series platform. Installation is straightforward: drop your existing P320 Fire Control Unit into the TXG module, and you're ready to shoot. The grip is sized for medium hands and is compatible with full-size and X5 slide assemblies.
One critical compatibility note: the TXG grip module is designed to work with newer SIG SAUER magazines featuring the circular SIG SAUER logo and square locking tab on the basepad. Older-style magazines with circular locking tabs will require modification to fit properly. If you're running legacy mags, SIG offers newer basepads and locking plates separately to bring your magazines up to spec.
