## What Customers Say

*AI-generated insights from customer reviews*

Owners of the P365X with the ROMEO-RS optic consistently point to the factory-mounted red dot as the main draw. Getting a zeroed optic straight out of the box removes the fitting guesswork, and most find the XRAY3 backup sights genuinely usable if the dot ever goes down.

The micro-compact frame divides opinion when it comes to sustained shooting. Smaller hands tend to rate it highly for carry comfort, while shooters with larger hands find the grip a touch short for controlled rapid fire. The 10-round flush magazine is the trade-off for the slim profile.

On value, the P365X ROMEO-RS bundle is seen as a fair deal compared to buying the optic separately. The Nitron finish holds up well to holster wear in most accounts, though a few owners note the optic housing shows contact marks faster than the slide itself.
