Designed around the modular P365 fire control unit, the FUSE variant accepts the full range of P365 slides and grip modules, making future customization straightforward.
The lengthened, carbon-steel barrel improves sight radius and velocity while the optic-cut slide accepts Shield RMS-c and SIG-LOC footprint red dots straight from the box.
Front and rear serrations plus weight-saving lightening pockets give the Nitron-finished slide fast, positive manipulation without excess mass.
The nickel-plated, flat-faced striker trigger delivers a consistent pull and quick reset, complemented by an integral accessory rail for lights or lasers.
An LXG laser-textured grip with flared magwell speeds reloads and locks the pistol firmly in the hand despite its micro size and 21-round capacity.
