## What Customers Say

*AI-generated insights from customer reviews*

The P365 Fuse owners are generally pleased with the Romeo-X optic included from the factory. Getting a pistol and optic as a matched system at a single price point is a frequent highlight in owner feedback. The 21+1 capacity in a compact-size package is also a recurring point of satisfaction.

The 4.30-inch barrel gives the Fuse a slightly longer sight radius than the standard P365, and striker-fired shooters adapt to it quickly. The beavertail on the frame gets positive mentions for grip comfort and reducing muzzle flip.

Some owners find the overall package larger than expected for a P365 variant, which affects concealability compared to the base model. The Romeo-X dot size and zero retention after hard use are minor concerns that appear in mixed owner reports.
