The P365 FUSE configuration pairs a 4.3 in DLC-coated carbon-steel barrel with a stainless-steel slide in Nitron black. This long-slide setup balances concealability with extended sight radius and velocity, while front and rear serrations aid slide manipulation.
The slide is optics-ready with an RMSc-footprint cut and an installed cover plate, giving you direct-mount compatibility without additional plates. Factory sights consist of a green fiber-optic front and a plain black serrated rear, yielding a bright front reference and an approximate 6 in sight radius.
Ergonomics are enhanced by the LXG laser-engraved grip texture and interchangeable S/M/L backstraps to fine-tune fit. A removable flared magwell comes installed to speed magazine changes. The true 1913 accessory rail with three slots supports common weapon lights or accessories.
