Introduced in 2024, the P365-FUSE is designed as a crossover carry variant, offering one of the longest sight radii in the P365 family. This pistol is striker-fired with locked-breech operation and is chambered in 9mm Luger. The case label on this example is dated September 27, 2024, confirming its recent production timeline.
The 4.3 in carbon steel barrel uses a DLC finish, while the stainless steel slide wears a Nitron black finish. The slide features front and rear cocking serrations, forward relief cuts, and an optic cut with a cover plate using the Shield RMSc-type footprint.
The black polymer grip module carries LXG laser-engraved texture for confident handling. Interchangeable backstraps and a removable flared magwell allow quick configuration. An M1913 accessory rail is integrated for mounting compatible lights or accessories.
Sight alignment is fast and clear with a fiber-optic front and a black serrated rear notch. The flat-faced, nickel-plated trigger provides a consistent press. Despite its extended barrel, the pistol maintains a slim 1.1 in width and an overall length of 7.2 in. Capacity is 21+1 with the included extended magazines, and a 17-round magazine is also provided.
