Full-size firepower, micro-compact footprint. Born from the P365 lineage, the all-new FUSE blends duty-grade capability with everyday-carry concealability in a way no other pistol can.

Why the P365 FUSE Changes Everything

• 21 + 1 Capacity in a 1-inch Grip
  Three magazines included—(2) 21-rd extended and (1) flush-fit 17-rd—give you the firepower of a duty pistol without the bulk.

• Full-Size Accuracy, Compact Control
  A 6 7⁄8" optic-ready slide and 4.3" carbon-steel barrel stretch your sight radius, boost velocity, and tighten groups.

• ROMEO-X Enclosed Red Dot Included
  Factory-mounted circle-dot optic (shake-awake, night-vision compatible) lets you run the gun faster—right out of the box.

• X-Series Ergonomics
  Razor-thin 1.1" wide, standard-length polymer module with higher undercut and X-Texturing keeps recoil flat and controllable.

• Carry-Everywhere Build
  DLC-coated stainless FCU, carbon-steel barrel, and Nitron slide shrug off sweat, rain, and daily abuse.

• Day-Night Confidence
  Suppressor-height X-RAY 3 night sights co-witness with the ROMEO-X for a built-in back-up.
