Description
The P320 AXG Carry Medium Grip Module swaps out polymer for aluminum, giving your P320 the weight and feel of a traditional metal-frame pistol. If you've carried a P229 or other Sig all-metal gun, you'll recognize that solid, balanced feel right away. The module is precision machined with deep undercuts that give you a natural grip angle, paired with an extended beavertail that sits right in the web of your hand for better control and faster target reacquisition.
What Makes the AXG Carry Module Different
This is essentially the P320 Carry grip size but in aluminum instead of polymer. It accepts your existing P320 fire control unit, so there's no serialization headache to worry about. The machining is clean with no sharp edges, and installation is straightforward. The module comes fitted with interchangeable Hogue G10 grip panels in black and a medium black backstrap, so you get options without buying anything extra.
Real-World Performance and Feel
The added weight (compared to polymer) improves recoil management and helps with shot-to-shot recovery, especially in rapid fire. People who've made the swap consistently mention how much more refined the gun feels in hand. The aluminum frame gives you that classic handgun aesthetic while keeping all the reliability and modularity P320 owners rely on. The carry size keeps it compact enough for concealment without sacrificing full grip purchase.
Compatible with 9mm, .357 SIG, and .40 Auto slides and barrels. Works only with non-manual-safety fire control units. Requires standard Carry-size or Full-size P320 magazines, not Compact size.

Frequently Asked Questions
Will the P320 AXG Carry grip module work with my P320 FCU?
Yes, as long as your fire control unit does not have a manual safety. The AXG Carry module is designed for non-manual-safety FCUs only. You'll simply drop your FCU into the module. Magazine compatibility depends on your FCU caliber, which must be 9mm, .357 SIG, or .40 Auto.
What magazines work with this grip module?
You'll need Carry-size or Full-size P320 magazines. Compact and Sub-Compact P320 magazines are too short and won't work properly with this module.
How does the aluminum AXG module change the gun's performance?
The added weight improves recoil control and balance compared to polymer grips, helping with shot-to-shot speed and accuracy. The module's precision machining and extended beavertail ergonomics provide better grip consistency and control in your hand.
Do I need a gunsmith to install this grip module?
No, it's a straightforward drop-in install. Simply remove your existing P320 grip module and press your FCU into the AXG module. No special tools or gunsmith work required.
