SIG Sauer P365 X-Series Optic Ready 9mm Pistol - 4.3" - Bronze - 2x 21rd, 1x 17rd Mags

The SIG SAUER P365 Fuse takes the P365 platform to its fullest expression — a 4.3-inch barrel, 21-round flush capacity, Macro-Compact grip module with standard 1913 Picatinny rail, and integral compensated slide, in a package that still carriers at 1.1 inches wide. The FDE slide over black frame gives the Fuse a distinct two-tone field aesthetic that sets it apart from the all-black standard configuration.

The SIG SAUER P365 Fuse is a striker-fired semi-automatic pistol chambered in 9mm Luger, built on a black Macro-Compact polymer frame with a Flat Dark Earth Nitron-finished stainless steel integral compensated slide and 4.3-inch carbon steel barrel.

The 4.3-inch barrel provides meaningful velocity advantage over the 3.1-inch variants and a longer sight radius for improved accuracy at distance, while the integral compensator machined into the slide reduces muzzle rise for faster sight picture recovery between shots. The Macro-Compact grip module features a standard 1913 Picatinny accessory rail that accepts any standard-footprint light or laser without proprietary adapters — a significant practical advantage over the SIG-specific rail on smaller P365 variants. The grip module accommodates the full-size 17-round flush magazine as its standard capacity and scales up to 21-round extended magazines without modification. X-RAY3 day/night sights provide a tritium-lit iron sight baseline at any light level. The flat XSeries trigger delivers the P365's characteristic crisp striker-fired pull. The serialized Fire Control Unit (FCU) makes the Fuse fully modular — grip modules, slides, and barrels swap without tools for a different configuration or caliber. Two 21-round and one 17-round magazine are included. Backed by SIG SAUER's Infinite Guarantee.
