SIG SAUER® P365-FUSE COMP RXSL Pistol / 9mm Luger

The SIG SAUER P365-FUSE COMP RXSL is a striker-fired 9mm pistol featuring an integrated compensator and a factory-installed ROMEO-X SIG-LOC Compact enclosed reflex sight. Its 3.7" barrel and integrated expansion chamber are designed to reduce muzzle rise without adding an external muzzle device. The pistol also features XRAY3 day/night sights, a full-length grip module with interchangeable backstraps, a 1913 accessory rail, and three steel magazines.

Integrated Compensator

The extended slide incorporates an expansion chamber ahead of the 3.7" barrel. This integrated compensator redirects propellant gases to help reduce muzzle rise and improve control during rapid strings of fire while retaining the pistol’s standard overall profile.

Deep front and rear slide serrations provide a secure gripping surface for loading, clearing, and press checks.

ROMEO-X SIG-LOC Compact Enclosed Reflex Sight

The RXSL configuration comes with a factory-installed ROMEO-X SIG-LOC Compact enclosed reflex sight. Its sealed optical system protects the emitter from dust, debris, and adverse weather.

The SIG-LOC Compact bottom-mount interface positions the optic low on the slide, allowing the standard-height XRAY3 sights to co-witness through the optic window. The side-loading battery compartment allows battery replacement without removing the sight or disturbing its zero.

XRAY3 Day/Night Sights

XRAY3 day/night sights provide a conventional backup sighting system in both bright and low-light conditions. Because the SIG-LOC optic sits low on the slide, suppressor-height sights are not required for co-witnessing.

Full-Length Grip Module

The polymer grip module combines the slim P365 platform with the handling characteristics and magazine capacity of a larger pistol. Interchangeable small, medium, and large backstraps allow the grip profile to be adjusted to the shooter’s hand.

A standard 1913 accessory rail accepts compatible weapon lights and other frame-mounted accessories.

Striker-Fired Fire Control System

The pistol uses a striker-fired operating system with a flat trigger shoe. This configuration does not include a manual safety. The stainless-steel fire control unit has a Black DLC finish, while the stainless-steel slide is protected by a Nitron finish.

17- and 21-Round Magazines Included

The pistol comes with one 17-round steel magazine and two 21-round steel magazines. This provides full-size ammunition capacity while retaining the modular dimensions of the P365 platform.
