P320 AXG Legion 9MM 3.9 inch barrel 21 Round Legion Gray with Night Sights

SIG SAUER P320 AXG LEGION 9mm Pistol

The SIG SAUER P320 AXG LEGION combines the modular P320 operating system with an all-metal Aluminum X-Series Grip (AXG) module and LEGION-series performance features. This exact model, manufacturer part number 320AXGF-9-LEGION, is chambered in 9mm and includes a 3.9-inch barrel, a full-size Legion Gray AXG grip module, an optics-ready slide with integrated porting, XRAY3 day/night sights, and three 21-round steel magazines. Its UPC is 798681678624.

SIG SAUER introduced the P320 AXG LEGION as a performance-focused configuration for shooters who prefer the balance, rigidity, and substantial feel of a metal grip module. The aluminum AXG frame is finished in custom LEGION Gray Cerakote and fitted with black LEGION-embossed G10 grip panels. A deep undercut, extended beavertail, and carefully shaped grip area are intended to support a high, consistent hold while retaining the familiar P320 control layout.

Integrated Porting and Full-Size AXG Grip

The slide uses an integrated expansion-chamber design with two top ports. Working together with the mass of the aluminum grip module, this arrangement is designed to reduce muzzle movement and felt recoil. SIG SAUER states that the combined system delivers a 30 percent reduction in felt recoil compared with its standard configuration. The 3.9-inch barrel remains within a full-size grip and slide package, producing an overall length of 8.2 inches.

Enhanced front and rear slide serrations provide defined grasping surfaces for loading and administrative handling. The optic-ready slide is optimized for SIG SAUER ROMEO1Pro and ROMEO2 optics, while the installed XRAY3 day/night sights remain useful when an electronic sight is not fitted. Optic fit, screw selection, and sight co-witness can depend on the optic and mounting hardware, so installation should follow the optic and pistol manufacturers’ instructions.

LEGION Controls and Handling Features

A skeletonized flat trigger provides the straight trigger face associated with SIG SAUER’s X-Series pistols. The full-size AXG module also incorporates a removable magazine well for a broad, guided opening during reloads. Black G10 grip panels add texture without replacing the solid feel of the aluminum module, while the extended beavertail helps establish repeatable hand placement.

This pistol ships with three 21-round steel magazines. The listed capacity is 21 rounds in the magazine plus one in the chamber when loaded in accordance with the owner’s manual. Magazine capacity and firearm availability may be restricted by state or local law; buyers should confirm current requirements before ordering.

Designed for Range and Performance Use

The P320 AXG LEGION is suited to shooters seeking a full-size, optics-ready 9mm pistol with factory recoil-management features and the weight distribution of a metal grip. Its 36.1-ounce weight with magazine, 1.6-inch overall width, and 5.5-inch overall height give it a stable, substantial profile. The integrated porting, flat trigger, removable magazine well, night sights, and three included magazines make the configuration especially well equipped for structured range practice and performance-oriented use.

As with any firearm, read the supplied manual before use, follow all safety rules, confirm that ammunition is the correct caliber, and use eye and hearing protection. Firearms should be stored unloaded and secured against unauthorized access. Any accessory installation or maintenance beyond normal field stripping should be completed according to SIG SAUER guidance or by a qualified professional.
