The P365-FUSE COMP ROMEO-X SIG-LOC™ delivers full-size shootability in a streamlined P365 platform, pairing a slide-integrated compensator with a factory-mounted enclosed optic for maximum control and confidence. A slide-integrated expansion chamber paired with a 3.7” barrel reduces recoil and muzzle rise without adding length, giving the FUSE the flatter shooting performance the platform was built for. Aggressive FUSE slide serrations ensure positive manipulation in any condition. The pistol comes equipped with a ROMEO-X SIG-LOC Compact optic, fully enclosed, sealed, and gas-purged for durability and all-weather performance. Mounted from underneath using the SIG-LOC system, it delivers the strongest optic lockup in the industry with a low deck height for standard-height iron sight co-witness. A polymer grip module with 1913 accessory rail, interchangeable backstraps, and X-RAY3 day/night sights round out a pistol designed for hard use and fast shooting right out of the box.
