## What Customers Say

*AI-generated insights from customer reviews*

Owners of the P365X generally find it reliable once broken in, and the compact size doesn't seem to hurt its ability to run a range of 9mm Luger ammunition. A common complaint is that a factory-mounted optic like the Romeo-X sometimes needs re-zeroing after a lot of carry use.

The P365X's grip is a common talking point: most shooters like how it conceals for a gun this size, though a few larger-handed owners wish the grip module were longer. The optic-ready slide is popular for a red-dot equipped carry gun without a separate milling job.

Aftermarket support for the P365 line is strong, so P365X owners can usually find holsters cut for the Romeo-X and spare magazines without trouble. Some buyers feel the factory optic package costs more than buying an iron-sighted P365X and adding a red dot separately.
