Designed as a P365 crossover, the FUSE stretches sight radius with a 4.3 in carbon steel barrel with a bright silver finish and a matching extended slide. Overall dimensions are 7.2 in L, 1.1 in W, and 5.7 in H, with a listed weight of 24.8 oz, retaining the carry-friendly width while adding length where it matters.
The slide is stainless steel with a black Nitron finish and features front and rear serrations, lightening cuts, and an RMSc optic footprint concealed by a two-screw cover plate. Sights are a green fiber-optic front blade paired with a plain black serrated rear for a crisp, high-contrast sight picture.
The striker-fired Fire Control Unit is stainless steel with a black DLC finish. A flat-faced, nickel-plated trigger provides a straight press. The polymer grip module is the LXG laser-engraved X-grip with a flared magwell for smooth reloads, and the frame includes an accessory rail.
Capacity is 21+1 with the included magazines (two 21-round and one 17-round steel mags). These magazines are P365-series compatible, including extended-length and shorter-length variants. This pistol is made in the USA, with markings including Newington, NH on the frame and caliber designations on the barrel hood; the factory MPN for this configuration is 365XF-9-BFO.
