Owners of the P365XL regularly point to the 12-round capacity in a subcompact package as its strongest selling point. The XL grip extension over the standard P365 is a meaningful improvement for shooters with medium to large hands, and most find it comfortable to carry despite the higher capacity.

The optics-ready cut gets a lot of use in practice. A large portion of P365XL buyers add a small red dot and report the combination works well for concealed carry. The XRAY3 sights are good enough to use without an optic, which keeps the out-of-box experience solid.

The P365XL draws mild criticism around its trigger reset, which some shooters describe as longer than expected for a pistol at this price point. A few owners also note the grip texture is on the aggressive side for all-day carry against bare skin. Overall the platform has a dedicated following, but it is not universally loved.
