Sig Sauer P365 Fuse 9mm Compact Optic Ready

The Sig Sauer P365 Fuse: Concealment Meets Capability

The P365 Fuse represents a thoughtful evolution of Sig Sauer's acclaimed compact carry pistol. It strips away unnecessary complexity while adding genuine utility for the modern defensive shooter.

Core Design Philosophy

Built on the proven P365 platform, the Fuse combines a fiber optic front sight with an optic-ready slide, giving you flexibility in how you configure your sights. The nickel-plated flat-faced trigger breaks cleanly and predictably. The laser-stippled X-Grip module measures just 1 inch wide—genuinely thin for deep concealment.
