Sig Sauer P365 AXG Legion Pistols

SIG P365 Legion Pistols

The SIG P365 AXG Legion is the metal-grip Legion P365. SIG puts an alloy AXG grip, Legion Gray, and Legion furniture on the P365 so it still conceals like a P365 and fills the hand like a metal gun. The AXG Legion uses a 3.1 in. barrel, an optic-ready slide, and XRAY3 sights. A factory red dot is installed only when this page says so. These pistols ship to a licensed FFL.

These pistols are for buyers who want the capacity and carry role of a macro-compact P365 with a heavier metal grip than the polymer P365, P365X, P365-XL, and P365-XMACRO models. They are not P320 AXG Legion pistols. The P320 AXG Legion is a larger P320 with a longer slide and P320 magazines.

AXG Metal Grip Module vs Polymer P365 Models

AXG is SIG’s alloy XSeries grip module. On the P365-AXG LEGION, that module is an aluminum-alloy grip with a magwell and interchangeable custom G10 chevron panels. SIG lists the grip color as Legion Gray and the slide as stainless steel with a Legion Gray Cerakote finish.

Compared with a polymer P365-XMACRO COMP, the AXG Legion is wider and heavier. SIG lists 1.4 in. overall width and 26 oz. for the iron-sight 17-round and 10-round pistols, versus 1.1 in. and 21.5 oz. for the polymer XMACRO COMP. Barrel length and overall length match that compensated XMACRO COMP at 3.1 in. and 6.6 in. The extra mass and G10 panels are the point of the metal-frame P365, not a longer barrel.

Legion Features on the P365

SIG describes the P365-AXG LEGION as the first P365 in the Legion series. SIG lists a two-port integrated expansion chamber in the slide, an optic-ready slide with enhanced serrations, XRAY3 day/night sights, a flat striker-fired trigger, a 1913 Picatinny rail, and a non-threaded carbon-steel barrel. The expansion chamber is part of the slide, not a muzzle device on a threaded barrel.

Factory optic cuts are not all the same. Iron-sight models use the Compact (Shield RMSc) footprint. The ROMEO-X SIG-LOC package uses SIG’s SIG-LOC Compact interface. Confirm the exact slide cut before buying a separate red dot. A Compact-footprint sight is not automatically a SIG-LOC sight, and the reverse is also true.

P365 AXG Legion Models

The 17-round P365 AXG Legion is the standard Legion Gray pistol with three 17-round steel magazines and no factory optic. The 10-round P365 AXG Legion is the same iron-sight, no-manual-safety pistol with three 10-round magazines. It is not the California manual-safety model.

Two factory-optic pistols add a ROMEO-X Compact-class red dot. The P365 AXG Legion with ROMEO-X SIG-LOC Compact is SIG’s current factory package: SIG-LOC Compact footprint, electro-optic installed, 5.8 in. height, and 27.2 oz. The P365 AXG Legion with ROMEO-X Compact is the 17-round factory-optic variant, model 365AXGCA-9-LEGION-RXX, with a Compact-footprint ROMEO-X Compact on the slide. The California-compliant P365 AXG Legion adds a manual safety and ships with three 10-round magazines.

How It Compares to Other P365 Pistols

The broader P365 collection covers polymer micro-compact pistols with shorter grips. P365-XMACRO pistols use the longer polymer macro-compact grip without the alloy module, G10 panels, or Legion Gray package. P365-XMACRO COMP pistols share the 3.1 in. compensated-slide format and 17-round magazine pattern, but they remain polymer-framed, list a 1.1 in. width, and typically include two magazines rather than three.

A P365-FUSE is a longer P365, not a metal-framed Legion. If you are shopping full-size Legion pistols, see SIG Sauer P320 pistols for the P320 AXG Legion. That pistol uses the P320 fire-control unit and P320 magazines. Related ROMEO-X sights are listed in the ROMEO-X collection.

Choosing a P365 AXG Legion

Choose the 17-round iron-sight pistol if you want the standard Legion carry setup and will add a Compact-footprint optic later, or run XRAY3 sights alone. Choose the 10-round iron-sight pistol for magazine-capacity limits without a manual safety. Choose the SIG-LOC factory-optic pistol if you want the red dot installed on SIG’s SIG-LOC Compact cut. Choose the ROMEO-X Compact factory-optic pistol if you want a Compact-footprint ROMEO-X already mounted. Choose the California-compliant pistol only when you need the roster configuration with a manual safety and 10-round magazines.

Holsters should be specified for the P365-AXG LEGION. The alloy module and G10 panels make the pistol wider than a polymer XMACRO, so do not assume an XMACRO holster will fit. SIG lists a dedicated AXG Legion 17-round magazine as compatible with P365-XMACRO, P365-FUSE, P365-DH3, and P365 FLUX pistols; confirm capacity rules before ordering extra magazines.

These pistols are standard handguns and must ship to a licensed FFL dealer. Confirm magazine capacity, optic footprint, safety configuration, and state restrictions on the exact model before you order.
