Norsso N365-FUSE 4.3" 9mm E Port Barrel

This FUSE barrel uses Norsso's inline E-pattern gas ports instead of the C-port layout, cut into 17-4 stainless for a flatter-shooting, better-controlled follow-up shot than the factory barrel offers. It only fits Norsso's matching Reptile KP and Rail KP FUSE slides, so it's built for a specific ported-slide setup rather than a universal upgrade.

Fitment notes: Inline elliptical (E-pattern) gas ports, cut for the matching Norsso comp slides only.

Heads up: P365-FUSE Reptile KP, P365-FUSE Rail KP. NOT compatible with any SIG factory slide or any other manufacturer's slide.
