P365 FUSE 9MM 4.3" 21+1 ROMEO

The SIG SAUER P365-FUSE is a semi-automatic pistol chambered in 9mm Luger. It is built on a polymer frame finished in black oxide with matching black polymer grips. The pistol uses a striker-fired trigger system and is configured with a standard magazine capacity of 21+1 rounds. A 4-inch barrel provides a balance between compact handling and extended sight radius within the P365 lineup. The barrel is not threaded, maintaining a streamlined profile consistent with its concealed-carry dimensions.

Factory-equipped adjustable sights are specified as “other adjustable sights,” allowing modification of point of aim. The black oxide finish produces a uniform, non-reflective surface across the frame and slide. The striker-fired mechanism contributes to consistent trigger operation, and the polymer frame construction supports reduced weight and structural durability. The overall configuration places the P365-FUSE in the compact category of the series while retaining the higher capacity associated with extended models.

The pistol includes a ROMEO optic configuration integrated with the firearm, combining optical sighting capability with the adjustable mechanical sights. No threaded muzzle or additional accessory mounts are listed. No further accessories or packaging details are specified beyond the core firearm setup. The combination of polymer frame, black oxide finish, adjustable sights, and ROMEO optic setup defines this model’s configuration within the P365 family.
