## What Customers Say

*AI-generated insights from customer reviews*

Owners of the P365 Fuse generally appreciate having the Romeo-RS red dot included at the purchase price rather than sourcing one separately. The LXG grip module draws consistent praise for its texture and feel compared to the standard grip. Most find the 4.3-inch barrel a practical step up from the original P365 without adding too much bulk.

The trigger on the Fuse gets mixed feedback. Some owners find it crisp out of the box; others want a shorter reset and end up swapping components. The optics footprint is specific to the Romeo-RS, so those wanting a different red dot may need an adapter plate.

Value opinion is divided. Buyers who wanted the Romeo-RS anyway consider it a good package deal. Those who already own a preferred optic feel they are paying for hardware they will not use. Magazine compatibility with the broader P365 lineup is a plus most mention positively.
