Owners of the P365 FUSE generally praise the magazine capacity relative to the P365 platform size. Getting 21-round capacity in the FUSE format is the primary draw, and most agree the included magazine lineup makes it ready to use without additional purchases.

The 4.3-inch barrel gives the FUSE a longer sight radius than standard P365 variants, which shooters find helps with precision at distance. The Coyote finish gets consistent positive comments for durability and appearance, though some find it more conspicuous than black for concealed carry.

The 2A FUSE carries a premium over base P365 models, and whether that premium is justified is where opinions diverge. Trigger feel is consistent with the P365 family, which most owners consider adequate though not exceptional.
