Sig Sauer P320 X-Series TXG Medium Grip Module, Tungsten Infused, Full Size, 9mm Luger, Fits 4.70" Barrel

The Sig Sauer P320 X-Series TXG Medium Grip Module brings a unique engineering solution to shooters looking to tame recoil and improve control on their full-size P320. Built with tungsten-infused polymer using a patent-pending manufacturing process, this grip module combines the heft and recoil-dampening properties of steel with the flex and comfort of polymer. The result is one of the flattest, softest-shooting grip modules available for the P320 platform—a meaningful upgrade if you're running high-round-count sessions or demand a softer shooting experience without sacrificing ergonomics.

This is a medium-length grip module designed for full-size P320 platforms with a 4.70" barrel. It weighs 13.3 ounces and requires a complete P320 Fire Control Unit and an X5 or full-size slide assembly to function as a complete pistol. The tungsten infusion shifts the balance and recoil impulse noticeably compared to standard polymer modules, making it a smart choice for shooters who appreciate the physics of weight distribution and damping in their carry or competition guns.

A critical compatibility note: this grip module is designed to work only with newer-style P320 magazines that feature a circular Sig Sauer logo and a square locking tab on the basepad. Older magazines marked with circular locking tabs will require modification to fit properly. If you're building or upgrading a P320, confirm your magazine generation before ordering. Newer basepads and locking plates are available separately if needed.

Frequently Asked Questions

What do I need to complete a P320 using this grip module?

You'll need a complete P320 Fire Control Unit and an X5 or full-size slide assembly. The grip module is a component, not a complete firearm.

Will my existing P320 magazines work with this grip module?

Only newer-style P320 magazines with a circular Sig Sauer logo and square locking tab on the basepad will work without modification. Older magazines with circular locking tabs require modification to fit properly. Newer basepads and locking plates are available separately.

What makes the TXG grip module different from a standard P320 grip?

The TXG uses a patent-pending tungsten-infused polymer process that gives it the weight and recoil-dampening characteristics of steel while maintaining the flexibility of polymer. This results in a softer, flatter-shooting experience compared to standard polymer grip modules.

What slide assemblies are compatible with this medium grip module?

This grip module is designed to work with X5 and full-size P320 slide assemblies and is specifically sized for a 4.70" barrel configuration.
