Sig Sauer 8901005 P320 Tungsten Gray Polymer Grip Module for Sig P320

The Sig Sauer P320 Tungsten Gray Polymer Grip Module is a full-size grip frame engineered to transform how your P320 feels and performs at the range. Built with a tungsten-infused polymer compound and finished with aggressive laser stippling, this grip module delivers the weight and substance of steel combined with the damping characteristics of modern composite materials — resulting in a shooter-friendly platform that significantly reduces felt recoil and muzzle rise. If you're running a P320 and want a softer shooting, more controllable pistol without a complete rebuild, this module is the foundation that makes it happen.

Installation is straightforward: drop your existing P320 Fire Control Unit into this grip module, pair it with your Full-Size or X5 slide assembly, and you're ready to shoot. The laser-engraved surface provides confident purchase in all conditions — wet hands, gloved shooting, rapid strings — without the grip peeling away from your palm. The tungsten-infused construction gives the module genuine substance; you'll feel the difference in hand.

This is a platform build, not a one-and-done upgrade, so ensure you have a complete Fire Control Unit and compatible slide assembly before ordering. Magazine disconnect compatibility is built in, making this grip module adaptable to your existing P320 ecosystem. For shooters looking to dial in a truly flat, controllable full-size P320, the tungsten gray finish paired with aggressive stippling creates a no-nonsense duty or range gun foundation.

Frequently Asked Questions

What do I need to install this P320 grip module?

You'll need a complete P320 Fire Control Unit and either an X5 or Full-Size slide assembly. The grip module is the frame portion only and requires these components to function as a complete pistol.

Is this grip module compatible with P320 X5 and Full-Size slides?

Yes. This full-size grip module is designed to work with both P320 X5 and Full-Size slide assemblies.

Does this grip module support magazine disconnect functionality?

Yes, the P320 Tungsten Gray Polymer Grip Module is magazine disconnect compatible.

What's the difference between tungsten-infused polymer and standard polymer grips?

This grip module uses a tungsten-infused polymer that combines the weight and recoil-dampening properties of steel with the flexibility and durability of modern polymer. The result is increased substance and a softer-shooting platform compared to standard polymer-frame pistols.
