Sig Sauer P320 X-Series TXG Tungsten Grip Module (Small) - Fits Full Size P320, 9mm/.40 S&W/.357 Sig

The Sig Sauer P320 X-Series TXG Tungsten Grip Module in Small size is a tuning part purpose-built for shooters who want to reduce recoil and muzzle flip on their full-size P320 platform pistols. The TXG uses a tungsten-infused polymer construction—a patent-pending process that combines the substantial weight of steel with the dampening properties of polymer. The result is measurably flatter shooting behavior, softer felt recoil, and improved control during rapid fire or precision work at distance.

This grip module is designed as a direct replacement for your stock P320 grip frame and accepts your existing Fire Control Unit (trigger assembly, sear, springs) from your current pistol. It's compatible with full-size P320 slide assemblies and works with P320 X5 slides as well. The module itself weighs 13.3 oz, and with a compatible magwell installed, the complete assembly reaches 16.6 oz. The added mass downrange transforms how your P320 cycles, reducing unwanted movement between shots and making follow-ups faster and more accurate.

Whether you're running your P320 at the range, in competition, or as a field pistol, the TXG module is a straightforward way to upgrade recoil management without a full gun replacement. Installation is simple: remove your current grip module, install the TXG, and drop your Fire Control Unit into it. You'll need a compatible full-size or X5 slide assembly and your own FCU to complete the build.

Frequently Asked Questions

What do I need to install this grip module on my P320?

You'll need your existing P320 Fire Control Unit (the trigger assembly and internal components) and a compatible full-size P320 or P320 X5 slide assembly. The grip module itself is the frame; install your FCU into it and mate it with your slide. A magwell is optional and not included.

Will the TXG grip module fit my P320 subcompact or compact?

No. This is the Small version designed for full-size P320 and P320 X5 slide assemblies only. Verify your slide assembly size before ordering.

Does this grip module reduce recoil and improve accuracy?

Yes. The tungsten-infused polymer construction adds substantial weight and absorbs recoil energy, resulting in flatter shooting behavior and reduced muzzle flip. This translates to faster follow-up shots and easier sight tracking on target.

Is the magwell included?

No. The grip module does not include a magwell. The 16.6 oz specification assumes a magwell is installed; the module alone weighs 13.3 oz.
