Description
The SIG Sauer P320-AXG COMBAT is a full-size pistol built on an alloy XSeries grip module, giving you the low bore axis and weight of a metal frame with the modularity of the P320 platform. This rig is for shooters who want a duty-grade handgun that balances fast handling with reduced muzzle flip. We added this to our catalog in early 2024, and it’s been a reliable seller with consistently positive customer feedback. A key benefit: the alloy frame adds just enough heft to settle the gun without being a burden. Our staff note: “The weight is barely noticeable once installed. Under an ounce of added carry weight.”

What Buyers Ask
Does this fit standard P320 holsters?
It fits most full-size P320 holsters designed for a 4.7-inch barrel and a rail. The alloy grip is slightly wider than the polymer version, so you may need a holster with an open bottom or one molded for the AXG module. We carry several options that work.
Can I swap the grip module for a different size?
Yes, the P320-AXG COMBAT uses the standard P320 fire control unit, so you can swap to any P320 grip module—polymer, TXG, or another AXG size. The alloy module is specific to the AXG line, but it’s fully compatible with all P320 FCUs.
Is the barrel threaded? What thread pitch?
Yes, the barrel is threaded at 1/2×28, the standard for 9mm suppressors and compensators. It comes with a thread protector installed. The barrel is also compatible with most aftermarket muzzle devices that use the same pitch.
