Sig Sauer P320 AXG Full Size Aluminum Grip Module Assembly - 9mm, .357 Sig, .40 S&W - Black

The Sig Sauer P320 AXG Full Size Aluminum Grip Module Assembly brings the solid feel and refined aesthetics of a metal-frame pistol to the modular P320 platform. Built around a precision-machined aluminum grip frame, the AXG module lets you install your existing P320 firing control unit (FCU) into a platform that shoots and feels like a classic—without starting from scratch. This is a no-nonsense upgrade for shooters who want the control and pointability of a heavier, metal grip without sacrificing the versatility that makes the P320 system so popular.

The grip module itself is engineered for shootability: deep undercuts and an extended beavertail work together to lock your hand in place and reduce muzzle rise during rapid fire. The ergonomic profile feels natural in both typical and high-grip-tang positions, and the included Medium Black back strap and interchangeable black G10 grip panels (by Hogue) let you dial in your personal fit. Whether you're running this for competition, duty carry, or precision work on the range, the AXG gives you a mechanical anchor point that aluminum-framed predecessors proved, again and again, actually works.

Compatible with 9mm, .357 SIG, and .40 S&W slides and barrels, the AXG module opens the door to building multiple configurations from one FCU—a real advantage for shooters who like to optimize for different roles or barrel lengths. The black anodize finish is built to last, and the machining quality reflects Sig's reputation for tight tolerances.

Frequently Asked Questions

What P320 parts do I need to use this grip module?

You'll need a P320 firing control unit (FCU) and a compatible slide and barrel assembly. The AXG grip module itself houses the FCU; the slide and barrel must match your desired caliber (9mm, .357 SIG, or .40 S&W).

Can I use this grip module with different caliber setups?

Yes. Because the modular P320 system separates the FCU from the grip and slide, you can swap different caliber slides and barrels onto this AXG grip module with the same FCU, giving you multi-caliber capability from one lower assembly.

What's included with the grip module?

The AXG Full Size module comes with a Medium black back strap and interchangeable black G10 grip panels manufactured by Hogue. Additional back straps and grip panels may be purchased separately if you want to further customize fit.

Is this grip module suitable for carry or duty use?

The AXG module is built on the full-size P320 platform and can be configured for carry or duty depending on your slide and barrel selection. The aluminum construction and extended beavertail are designed for control and fast shooting, making it adaptable to many roles.
