The SIG Sauer P365 FUSE is the next evolution of the P365 lineup—designed for shooters who demand maximum firepower, modular fit, and enhanced accuracy in a carry-sized package. At the core of this pistol is a 4.3-inch carbon steel barrel with DLC finish, engineered for smooth cycling and long-lasting performance.
Its optic-ready Nitron-finished stainless steel slide is cut for Shield RMSc footprint optics and features aggressive front and rear serrations. The fiber optic front sight paired with a blacked-out serrated rear provides excellent contrast for fast target acquisition—even in dynamic conditions.
The LXG (Laser Engraved X-Grip) polymer grip module ensures control and comfort, with laser-etched texture and ergonomic shaping. Interchangeable backstraps (small, medium, large) are included for a fully customizable feel. The pistol ships with two 21-round and one 17-round magazines, delivering serious capacity in a compact footprint.
