The P365-FUSE slide is optics-ready with an RMSc footprint; the optics cut is open with empty screw holes (no cover plate present), allowing a direct-mount micro-optic when desired. Forward and rear serrations provide confident slide manipulation. The sighting system pairs a green fiber-optic front post with a plain black rear notch for a crisp, daylight-friendly sight picture.
The grip module is polymer with LXG laser-engraved texture, a beavertail, and a factory flared magwell that is removable per factory literature. Interchangeable S/M/L backstraps tailor the fit. An extended slide catch and a push-button, reversible magazine release support efficient, user-configurable controls.
The 4.3 in carbon steel barrel uses a non-ported design with a DLC finish. The striker-fired system features a flat-faced, nickel-plated trigger. A 1913 Picatinny rail with three slots on the dustcover accepts compatible lights or accessories as needed.
Capacity is configured for up to 21+1 rounds of 9mm Luger, and this example includes two 21-round magazines plus one 17-round magazine (flush-fit and extended types present). Overall dimensions are 7.2 in long, 5.1 in high, and 1.1 in wide, with an approximate empty weight of 23.1 oz. Made in the USA; MSRP is listed at $779.99. MFG Part Number: 365XF-9-BFO.
