SIG SAUER P365 FUSE 9MM 4.3" 21+1 ROMEO-X PISTOL

Sig Sauer P365 FUSE 9mm 4.3" 21+1 w/ ROMEO-X Pistol

The Sig Sauer P365 FUSE blends full-size performance with micro-compact roots. Chambered in 9mm, this next-gen carry pistol features a 4.3" barrel, 21+1 capacity, and comes ready with a ROMEO-X red dot sight pre-installed. It’s built to dominate carry, duty, or competition—all in one platform.

Sig designed the FUSE to bridge the gap between a concealed carry pistol and a full-size fighting handgun. The longer slide boosts accuracy and control, while the modular grip module and flared magwell help you shoot faster and reload smoother.

Fusion of Size, Power, and Optics

The ROMEO-X red dot mounts directly to the slide and offers a crisp, fast sight picture. Suppressor-height X-Ray3 night sights give you backup and co-witness with the optic for all-light readiness.
