## What Customers Say

*AI-generated insights from customer reviews*

Owners of the P365X with the Romeo-RS package appreciate getting a ready-to-run optic setup without sourcing a separate sight. The combination of the XSeries grip and 12-round capacity is a common reason buyers choose this variant over the standard P365.

The 3.1-inch barrel draws mixed reactions: those who carry concealed find the compact frame easy to manage, while range shooters sometimes wish for a longer sight radius. The Romeo-RS optic gets decent marks for size and brightness, though a handful of owners report having to re-zero it after a few range sessions.

Value perception varies. Buyers who factor in the included optic and XRAY3 sights tend to feel the price is fair. Those who planned to mount their own optic feel they paid for hardware they did not want.
