The P365-FUSE format brings a longer 4.3-inch barrel and matching long slide to the P365 series, adding sight radius and an optics-cut slide while keeping the pistol slim and carryable. The slide uses a stainless steel construction with a Nitron finish and non-ported profile, paired with forward and rear serrations for positive manipulation.
Controls are straightforward: a striker-fired action with a flat-faced, nickel-plated trigger and standard left-side magazine release. This configuration has standard left-side controls and no external thumb safety.
The LXG-textured polymer grip module is matched with a removable bolt-on flared magwell to speed reloads and provide a secure hold. Included magazines deliver a maximum capacity of 21+1, with two 21-round magazines and one 17-round magazine supplied.
Sight equipment is clean and fast: a green fiber-optic front sight and a black square-notch rear. A multi-slot 1913-style accessory rail on the frame supports common lights or accessories. The pistol uses a locked-breech, tilting barrel operating system and is a recent release in the P365 lineup, manufactured in the USA by SIG Sauer, Inc., Newington, NH.
