Owners of the P365 AXG Legion are generally enthusiastic about what Sig built into this platform. The combination of the AXG metal grip module and the compensated slide gives the pistol a noticeably different shooting feel compared to the standard P365, and most owners who step up from a base P365 comment on the improved weight distribution and reduced muzzle movement. The Romeo X and XRAY3 sights are a recurring positive.

The compensated slide does divide opinion. Shooters who run it at indoor ranges note that the added blast is a real consideration. Others who compete or train outdoors find the compensation genuinely useful for fast follow-up shots at 3.1 inches of barrel. The trigger on the AXG Legion is generally well-regarded, though some owners find the reset shorter than they expect coming from other compact platforms.

On value, the P365 AXG Legion sits at a premium price point and most buyers accept that going in. The included Romeo X optic and three 17-round magazines are frequently cited as making the overall package feel justified. The aftermarket for the P365 family is deep, which owners appreciate for grip accessories, holsters, and magazine options.
