SIG Sauer P320-AXG Legion Full-Size 9mm with Integrated Slide Compensator
The P320-AXG Legion is the first metal-framed P320 to wear the Legion badge while adding SIG’s integrated dual-port compensator. Built on the precision-machined AXG alloy grip module and finished in Legion-gray Cerakote, this striker-fired full-size blends reduced recoil, premium X-Series features, and Legion exclusivity into one factory-tuned package.

What’s Included
- SIG Sauer factory hard case (gray)

The compensated 3.9-inch carbon-steel barrel vents through twin ports machined directly into the slide, cutting muzzle rise without the bulk of a threaded device. The Legion-gray slide is optics-ready and sports aggressive front and rear serrations for confident manipulation.
SIG’s AXG (Alloy XSeries Grip) module gives this P320 a solid alloy frame with interchangeable Hogue G10 Legion-pattern grip panels and a MIL-STD-1913 rail for lights or lasers. An extended removable mag-well funnel speeds reloads and works with both included 21-round and 17-round steel magazines.
The flat-face, skeletonized X-Series trigger breaks at roughly 4.5 lb and resets short for rapid follow-up shots. X-Ray3 day/night sights—fluorescent green front dot with tritium inserts and suppressor-height, serrated rear—co-witness with most micro red dots.
A modular, serialized fire-control unit allows caliber or size changes with compatible P320 conversion assemblies. Legion ownership also unlocks access to member-only accessories, app-based training, and advanced shooting events.
