P365 XMacro owners generally appreciate how the grip accommodates a 17-round magazine in a package that still conceals reasonably well. The XMacro grip module is longer than the standard P365, and that trade-off is the central debate: better capacity and control versus the smaller original footprint.

The XRAY3 sights are consistently praised for low-light use. The RMSc footprint cut is valued but limits optic choices compared to larger footprint pistols. The stainless slide finish shows wear more visibly than a standard black finish, which bothers some owners more than others.

The factory compensator on the TCOMP variant gets polarized feedback. Shooters who run it at speed like the muzzle control improvement. Those focused on concealed carry question whether the added length and complexity are worth it for a 3.1-inch platform.
