## What Customers Say

*AI-generated insights from customer reviews*

Owners of the P365 X-MACRO tend to praise Sig's fit and finish, noting slide-to-frame tightness and a trigger that feels a step above entry-level striker guns. A common complaint is the factory ROMEO-X optic needing a zero check out of the box, though most say it holds zero once mounted correctly.

The grip module carries well for a pistol with this much capacity, and the size lands between a compact and full-size carry gun, which some shooters like and others find a bit large for appendix carry. The enclosed optic housing gets mixed reactions: it protects the lens well but adds bulk compared to an open-emitter red dot.

The P365 platform has a large aftermarket, so owners appreciate easy access to holsters, magazines, and sights sized for the X-MACRO frame. The threaded barrel gets used often for suppressor hosts, and 9mm keeps ongoing ammunition costs reasonable.
