FUSE. Now Flatter.
The Compensated FUSE Has Arrived.
Introducing the P365-FUSE COMP ROMEO-X SIG-LOC — a full-size P365 platform engineered for shooters who want recoil control, optic durability, and out-of-the-box readiness. Featuring a slide-integrated expansion chamber with a 3.7” barrel, the FUSE COMP delivers reduced muzzle rise without added length or bulk.
Equipped with a factory-mounted ROMEO-X SIG-LOC Compact optic, fully enclosed and mounted from underneath the slide, the system provides the strongest optic lockup in the industry while maintaining a low deck height for standard-height iron sight co-witness.
FUSE slide serrations, a full accessory rail, and interchangeable backstraps ensure confident handling and adaptability across shooting styles.
Flatter shooting. Stronger lockup. Ready from day one
