SIG SAUER P365 FUSE Comp 9mm 3.7″ ROMEO-X SIG-LOC 17/21-Round

Description

SIG SAUER P365 FUSE Comp 9mm

The SIG SAUER P365 FUSE Comp expands the P365 family with a performance-focused configuration that combines a longer slide, integrated compensation and high-capacity magazines while maintaining the slim profile associated with the P365 platform.

Chambered in 9mm, this configuration features a 3.7-inch barrel, slide-integrated expansion chamber, factory-installed ROMEO-X SIG-LOC Compact enclosed optic, XRAY3 Day/Night sights and 17- and 21-round magazines.

Slide-Integrated Compensator

The defining feature of the SIG SAUER P365 FUSE Comp is its slide-integrated expansion chamber. The compensating system is designed to reduce muzzle rise and felt recoil without requiring an external compensator that increases the overall length of the pistol.

Combined with the 3.7-inch barrel, the compensated slide provides a flatter-shooting configuration designed for improved control and faster recovery between shots.

Factory-Installed ROMEO-X SIG-LOC Compact Optic

This P365 FUSE Comp comes equipped with a ROMEO-X SIG-LOC Compact enclosed red dot optic installed at the factory.

The enclosed optic is sealed and gas-purged for durability and uses SIG SAUER’s SIG-LOC mounting system. Its low deck height allows the optic to work with the pistol’s standard-height iron sights for co-witness capability.

3.7-Inch 9mm Barrel

The SIG SAUER P365 FUSE Comp uses a 3.7-inch carbon steel barrel paired with the longer compensated FUSE slide.

This arrangement allows the expansion chamber to be incorporated directly into the slide while keeping the pistol’s overall length to approximately 7.2 inches.

17-Round and 21-Round Magazines

The P365 FUSE Comp provides full-size ammunition capacity within the slim P365 architecture. It accepts both 17-round flush-fit and 21-round extended magazines.

This configuration includes one 17-round magazine and two 21-round magazines, giving shooters multiple capacity options directly from the factory.

XRAY3 Day/Night Sights

In addition to the factory-mounted red dot, the SIG SAUER P365 FUSE Comp features XRAY3 Day/Night sights.

The low mounting position of the ROMEO-X SIG-LOC Compact allows the factory iron sights to remain usable through the optic window.

Macro-Compact Polymer Grip Module

The P365 FUSE Comp uses a polymer macro-compact grip module designed to provide a full firing grip while retaining the narrow dimensions associated with the P365 family.

Interchangeable small, medium and large backstraps allow the grip to be adjusted to better accommodate individual hand sizes and preferences.

1913 Picatinny Accessory Rail

An integrated 1913 Picatinny rail provides mounting capability for compatible weapon lights and other accessories.

The standardized rail expands the versatility of the FUSE Comp and provides broader accessory compatibility than the proprietary rail found on some smaller P365 configurations.

Flat-Faced Striker-Fired Trigger

The SIG SAUER P365 FUSE Comp features a flat-faced trigger paired with SIG SAUER’s striker-fired operating system.

The streamlined control layout and consistent trigger system complement the pistol’s crossover design, providing familiar P365 operation in a larger and more performance-oriented configuration.

Full-Size Capability in the P365 Platform

The SIG SAUER P365 FUSE Comp bridges the gap between traditional micro-compact carry pistols and larger full-size handguns. Its 3.7-inch barrel, compensated slide, high-capacity magazines and factory-installed enclosed optic provide significantly more capability while retaining the slim dimensions of the P365 platform.

For shooters searching for a compensated P365 with a factory red dot and increased capacity, the FUSE Comp offers one of the most feature-rich configurations in SIG SAUER’s P365 lineup.
