SIG Sauer® P365-FUSE TACOPS 9mm Pistol with ROMEO-X® SIG-LOC™ Red Dot Sight

The SIG Sauer P365-FUSE TACOPS combines the extended-slide P365-FUSE platform with premium TACOPS features and a factory-installed ROMEO-X SIG-LOC enclosed red dot sight. Equipped with a 4.9-inch threaded barrel, removable magwell, extended slide catch, and four 21-round magazines, this configuration is designed for shooters seeking increased capacity, enhanced handling, and optics-ready performance while maintaining the slim profile that defines the P365 series.

Extended P365-FUSE Platform

The P365-FUSE TACOPS is built around the extended-slide FUSE platform, offering a longer sight radius and improved controllability compared to standard P365 models. The longer slide enhances sight alignment when using iron sights while preserving the compact grip dimensions and concealability associated with the P365 family.

Factory-Installed ROMEO-X SIG-LOC Optic

The pistol comes equipped from the factory with the ROMEO-X SIG-LOC enclosed red dot sight. Using SIG Sauer's proprietary SIG-LOC mounting system, the optic is secured from the underside of the slide, creating an exceptionally robust interface while maintaining an ultra-low mounting height. This design allows the factory XRAY3 Day/Night sights to remain fully functional and supports co-witness capability without requiring suppressor-height sights.

Fully Enclosed Red Dot Design

The ROMEO-X SIG-LOC features a sealed enclosed-emitter design that protects critical optical components from dirt, moisture, and debris. The optical system is nitrogen-purged and sealed to help prevent internal fogging caused by temperature changes and environmental conditions. A side-loading battery compartment allows battery replacement without removing the optic from the slide.

Four 21-Round Magazines Included

The TACOPS package includes four steel magazines with a capacity of 21 rounds each. High-visibility followers provide a clear visual indication when the magazine is empty, simplifying reloads and administrative handling.

Threaded Barrel and XRAY3 Sights

The pistol is equipped with a 4.9-inch threaded barrel compatible with suppressors and other muzzle devices. XRAY3 Day/Night sights remain visible through the optic window and provide a reliable backup aiming solution in both daylight and low-light conditions.

TACOPS Controls and Enhanced Handling

TACOPS-specific features include a removable flared magwell for faster magazine changes and an extended slide catch for improved manipulation. Combined with the high-capacity magazines and optics-ready configuration, these enhancements deliver many of the advantages of a full-size duty pistol in a slim, striker-fired platform.
