SIG SAUER P365-AXG LEGION RXSL 9mm Pistol

SIG SAUER P365-AXG LEGION RXSL 9mm Pistol

The SIG SAUER P365-AXG LEGION RXSL combines the compact P365 architecture with a metal AXG grip module, integrated recoil-mitigation system, and a factory-installed SIG-LOC Compact optic. This exact 9mm configuration uses a 3.1-inch carbon-steel barrel, a 17+1-round capacity, and three included 17-round steel magazines. It is intended for shooters who want the concealability of the P365 family with the added weight, balance, and rigidity of an alloy frame.

Manufacturer part number 365AXGCA-9-LEGION-RXSL and UPC 798681725236 identify the optic-equipped model. Those identifiers are important because SIG also offers P365-AXG LEGION pistols without an installed electro-optic, with 10-round magazines, or with different safety and footprint configurations.

Integrated Expansion Chamber

The stainless-steel slide incorporates a two-port integrated expansion chamber designed to redirect propellant gases and reduce muzzle movement. Because the chamber is built into the slide, the pistol retains its 3.1-inch barrel while gaining recoil-mitigation benefits without a separate threaded compensator. The slide also includes enhanced front and rear serrations for positive manipulation.

Reduced muzzle rise can help the shooter return the sights to the target more efficiently during controlled pairs and longer practice strings. Performance varies with ammunition and grip technique, so the shooter should still test the chosen practice or defensive load for function, accuracy, and point of impact.

Factory-Installed SIG-LOC Compact Optic

This RXSL variant includes a factory-installed SIG-LOC Compact electro-optic. The SIG-LOC mounting system establishes a low, secure interface between the slide and optic while preserving a low sighting plane. SIG pairs the optic with XRAY3 day/night sights, providing an immediate mechanical sighting reference if the electronic sight is unavailable.

The optic should be inspected for secure mounting and verified at the range before defensive use. Follow SIG’s instructions for battery replacement, brightness adjustment, zeroing, and mounting-screw torque. The exact SIG-LOC Compact footprint differs from standard Shield RMSc mounting, so replacement optics and hardware must be selected for this slide.

AXG Alloy Grip and LEGION Details

The AXG Macro grip module is machined from alloy and finished in LEGION Gray Cerakote. Custom G10 Chevron grip panels add texture and can be serviced separately from the frame. An extended magazine well helps guide magazine insertion, while the 1913 Picatinny rail accepts a compatible compact light or other appropriately sized accessory.

The additional weight of the alloy module places more mass in the shooter’s hand than a polymer P365 grip. This can produce a steadier feel during recoil while retaining an overall length of 6.6 inches and an overall width of 1.4 inches. The optic-equipped configuration measures approximately 5.8 inches high and weighs 27.2 ounces.

Flat Striker-Fired Controls

A flat-faced striker-fired trigger supports consistent finger placement. This model does not include a manual safety, so secure storage and a rigid holster that completely covers the trigger guard are essential. The pistol must remain holstered or unloaded whenever the trigger cannot be protected from unintended contact.
