The P365 AXG Fuse draws owners who want a compact platform with a longer sight radius and higher capacity than the standard P365. The 4.3-inch barrel is a meaningful upgrade over the original configuration, and the 21-round magazine option is a recurring reason buyers choose the Fuse over other P365 variants.

The AXG aluminum frame feels noticeably different from polymer-framed P365 models. Most owners prefer it for the added weight and reduced perceived recoil, though a few find the AXG frame makes the pistol slightly heavier than they prefer for all-day carry. The Black/Gray finish gets consistent positive attention for its appearance.

Optic compatibility is a key selling point, and owners who run a red dot on the Fuse tend to review the overall package well. Trigger feel matches other P365 AXG models, which satisfies most buyers but occasionally draws comment from shooters coming from other platforms expecting a different reset character.
