Key Takeaways

• The P365 AXG Legion features an alloy frame with integrated compensator and holds 17 rounds in a compact package

Overview of the Sig P365 AXG Legion

The P365 AXG Legion combines an aluminum alloy frame with compensated barrel technology and premium Legion series features to create a compact carry pistol that weighs 26 ounces with a magazine. This model bridges traditional metal-framed design with modern striker-fired performance in a package that holds 17 rounds.

What Sets the P365 AXG Legion Apart

The most distinctive feature of the P365 AXG Legion is its aluminum alloy frame, which replaces the standard polymer grip module found on other P365 models. This metal construction adds weight but provides a different shooting feel that some shooters prefer. The frame includes textured G10 grip panels that offer enhanced control compared to molded polymer textures.

The pistol comes factory-equipped with a compensated 3.1-inch barrel featuring ports that reduce muzzle flip during rapid fire. You get X-RAY3 day/night sights installed from the factory, along with an optics-ready slide cut for the Shield RMSc footprint. The compensator design sits integrated into the slide assembly rather than as an add-on component.

Three 17-round steel magazines come standard with the gun. The frame includes a flared magazine well that guides magazines during reloading, which helps when working with a compact pistol under stress. A Picatinny rail sits beneath the dust cover for mounting weapon lights or lasers.

Legion Series Heritage

The Legion designation represents Sig Sauer's premium product line with enhanced features and finishes. Legion series firearms carry specific upgrades including Legion Gray Cerakote finish, custom G10 grips, and enhanced triggers. The program started with full-size pistols before expanding to compact models.

You'll find the Legion Gray coating on both the slide and aluminum frame, creating a uniform appearance. The flat-faced Legion trigger provides a consistent pull that differs from standard P365 triggers. Every Legion model undergoes additional quality control steps during manufacturing.

The phrase "Carry What Defines You" serves as the Legion program's motto, emphasizing personalization and premium quality. Legion owners gain access to exclusive merchandise and community events through Sig Sauer's Legion program membership.

Intended Users and Applications

This pistol targets concealed carry permit holders who want metal frame construction in a micro-compact package. The 26-ounce loaded weight makes it heavier than polymer P365 models, which can help manage recoil but adds carry weight. Your choice between polymer and aluminum depends on whether you prioritize lighter weight or the feel of a metal frame.

The 17-round capacity and compensated barrel make the P365 AXG Legion suitable for personal defense where you need both concealability and firepower. The optics-ready slide accommodates red dot sights that improve target acquisition speed. Competition shooters in micro-compact divisions can use this pistol, though it's primarily designed for defensive carry.

Law enforcement officers looking for off-duty carry options will find the Legion features align with professional standards. The weapon light rail and night sights support low-light operations that duty use requires.

Key Features and Specifications

The P365 AXG Legion stands out with its aluminum alloy frame, integrated compensator, and 17-round capacity in a compact package. These features work together to create a pistol that balances shootability with concealment.

Alloy Macro Grip Frame and Ergonomics

The AXG grip module uses an aluminum alloy frame instead of polymer. This adds weight to the pistol but provides a different feel in your hand and changes how recoil transfers through the frame.

The frame measures 5.2 inches tall and 1.4 inches wide at the controls. Despite the metal construction, the pistol remains flat and easy to conceal.

Custom G10 grips attach to both sides of the aluminum frame. These black panels feature the Legion chevron logo and provide texture without being too aggressive on your hands or clothing. The G10 chevron grip panels are removable if you want to customize the pistol further.

The frontstrap and backstrap have checkering for additional grip. You'll also find checkering underneath the trigger guard. This area presses against your support hand index finger to help reduce side-to-side movement during firing.

Two Port Integrated Expansion Chamber

The P365 AXG Legion uses a 3.1-inch barrel that ends inside the slide. Forward of the barrel sits an expansion chamber with a two port integrated compensator machined into the top of the slide.

This design differs from traditional barrel-mounted compensators. The ports redirect gas upward as you fire, which provides recoil mitigation and reduces muzzle flip.

The compensator can reduce muzzle rise by 20 to 33 percent depending on your grip and ammunition choice. When combined with the weight of the aluminum frame, this helps the pistol feel more like a full-size gun during shooting.

The front sight sits behind the compensator ports. This positioning gives you a 5.1-inch sight radius, which falls between the original P365 at 4.9 inches and the P365 XL at 5.6 inches.

Trigger and Controls

The pistol uses a flat trigger that breaks at approximately 5.5 pounds. The flat face helps you press straight back without pushing the muzzle left or right. The trigger breaks at a near 90-degree angle for consistent performance.

Your slide catch lever is extended compared to standard P365 models. This makes it easier to drop the slide, though it's still a small control that requires deliberate thumb placement.

The magazine release is triangular, checkered, and made from steel. It's positioned for easy access and provides a positive surface for your thumb. This control is more consistent and easier to operate than the slide catch.

The pistol does not come with a manual safety as standard equipment. You get internal drop safety mechanisms but no external thumb safety lever.

Magazine Capacity and Extended Magwell

The P365 AXG Legion ships with three 17-round magazines. Each magazine features an aluminum basepad with serrations and the Legion chevron logo. These basepads extend slightly past the grip to ensure proper seating when you insert the magazine.

The 17rd magazine capacity gives you 17+1 rounds total. This represents a significant increase over the original P365, which held 10+1 rounds with its flush magazine.

An installed magwell comes factory-equipped on the aluminum grip module. The extended magwell is modest in size so it doesn't hurt your ability to conceal the pistol. The magwell guides magazines into the grip during reloads.

You can remove the magwell if you prefer. The magazines will still function without it, but you lose the reloading advantage it provides.

Slide and Sight System

The P365 AXG Legion features a compensated slide with integrated ports to reduce recoil and an optics-ready cut that accepts popular red dot sights. The pistol comes standard with X-RAY3 day/night sights that provide reliable aiming capability in any lighting condition.

Compensated Slide and Design

The integral compensated slide design includes a two-port integrated expansion chamber that redirects gas upward to counter muzzle rise. This built-in compensation system helps you maintain faster target acquisition during rapid fire.

The compensated slide measures 3.1 inches in length and maintains the compact profile needed for concealed carry. Unlike add-on compensators that increase overall length, this integrated design keeps the pistol compact while delivering recoil reduction benefits.

The compensation ports are machined directly into the slide assembly rather than attached as separate components. This approach ensures durability and eliminates the need for additional maintenance or adjustment. The system reduces felt recoil without requiring threaded barrels or aftermarket modifications.

Optics-Ready Slide and Enhanced Serrations

Your optics-ready slide accepts micro red dot sights using the standard mounting pattern. The optic cut sits low on the slide to maintain a natural sight picture and allows absolute co-witness with the iron sights.

The enhanced serrations run along both the front and rear of the slide. These aggressive cuts provide positive grip points for press checks and malfunction clearance. The serration pattern gives you secure purchase even with wet or gloved hands.

The slide features a durable steel construction with a Legion Gray Cerakote finish. This coating resists corrosion and wear while maintaining the distinct Legion aesthetic. The finish complements the aluminum grip module and creates a cohesive appearance.

X-RAY3 Day/Night Sights

The X-RAY3 day/night sights combine a high-visibility front sight with a blacked-out rear. The front sight features a tritium lamp surrounded by a bright colored ring that draws your eye naturally to the aiming point.

These sights work in complete darkness using self-illuminating tritium and provide enhanced visibility in daylight through the contrasting colored front ring. The rear sight uses a simple U-notch design without distracting dots or outlines.

The X-RAY3 system is designed to work alongside mounted optics rather than interfere with them. If your optic fails or runs out of battery, you can immediately transition to the iron sights without removing the red dot.

Performance and Handling

The P365 AXG Legion delivers notable improvements in shooting control through its compensated slide and aluminum construction. The metal frame changes how the pistol feels during extended shooting sessions, while its compact dimensions maintain practical everyday carry capability.

Recoil Control and Shooting Experience

The integral compensator reduces muzzle rise by 20 to 33 percent compared to non-compensated models. You'll notice the comp works by venting gas through two ports machined into the XL slide, creating downward pressure that keeps the pistol flatter during rapid fire.

The aluminum grip module adds weight that helps absorb recoil. At 26 ounces empty, the pistol feels heavier than polymer-framed competitors, but this extra mass translates to felt recoil similar to a full-size gun.

The 9mm caliber combined with the compensator makes follow-up shots faster and more controlled. The flat trigger breaks at approximately 5.5 pounds, providing a clean pull that doesn't disrupt your sight picture. Checkering under the trigger guard presses against your support hand finger to reduce lateral movement during strings of fire.

Carry Comfort and Concealability

The P365 AXG Legion measures 6.6 inches long, 5.2 inches tall, and 1.4 inches wide at the controls. The actual grip thickness stays around one inch, keeping the profile flat against your body.

The metal frame feels different from polymer when you carry it all day. Some shooters prefer the solid feel of aluminum, while others find the 26-ounce weight noticeable during extended carry periods.

The three-slot Picatinny rail accommodates lights without adding excessive bulk. The modest magazine well doesn't interfere with concealment under typical cover garments. You can carry what defines you as a defensive shooter with 17+1 rounds of 9mm capacity in a package smaller than traditional compact pistols.

Accuracy and Range Impressions

The 5.1-inch sight radius falls between the original P365 and the XL model. The X-Ray3 day/night sights feature tritium inserts with a lime green front ring that remains visible in varied lighting conditions.

The macro grip frame provides a full firing grip with all fingers on the gun. This longer grip improves control compared to subcompact models where your pinky hangs off the bottom.

The aluminum frame doesn't flex like polymer during firing, which creates a more predictable shooting platform. The combination of good sights, minimal muzzle rise, and a solid frame makes accurate shots easier at typical defensive distances and beyond. The pistol performs well for both precision shooting at the range and rapid engagement drills.

Customization and Accessory Compatibility

The P365 AXG Legion offers extensive customization through its metal frame design and standard mounting systems. You can upgrade optics, lights, grips, magazines, and holsters to match your shooting needs.

Optic and Light Mounting Options

The pistol features a Shield RMSc footprint optic cut that accepts micro red dot sights. You'll find the SIG ROMEOZero Elite is factory standard, but you can also mount the Holosun 507K X2 or Shield RMSc directly to the slide. These optics co-witness with the X-Ray3 Day/Night iron sights.

The AXG frame includes a true 1913 accessory rail for mounting weapon lights. This differs from earlier P365 models that used a proprietary rail system. The Streamlight TLR-7 Sub delivers 500 lumens and fits the rail perfectly.

The SureFire XSC is another popular choice with rechargeable capabilities. Both lights are designed specifically for the P365 platform and won't interfere with most holsters.

Grip and Frame Customization

The AXG frame comes with custom G10 grips that you can remove and replace. You can install different G10 panels from manufacturers like Hogue or SIG to change texture and appearance. Lambda offers polymer grip panels made in Colorado for all-condition performance.

The aluminum alloy frame provides a solid foundation compared to polymer versions. You can swap the entire grip module since it's compatible with all P365 FCUs except manual safety versions.

The magazine release is replaceable if you want to change size or style. Many shooters upgrade to extended magazine releases for faster reloads during competition or training.
