Sig Sauer P385-MACH3D 9mm Pistol 4" Barrel - 21 Rd - Nitron® Black

Sig Sauer P385-MACH3D 9mm Pistol 4" Barrel - 21 Rd - Nitron® Black

Representing the highest-performance expression of the P385 series, the SIG Sauer P385-MACH3D 9mm Optic-Ready Pistol brings together the brand's most advanced recoil-management technologies in a carry-focused package. Built around a factory-equipped MACH3D compensator attached to a 3.4-inch precision carbon steel bull barrel (4.0-inch total system length), this pistol dramatically redirects escaping gas to virtually eliminate muzzle flip and perceived recoil. Combined with an extremely low bore axis and the integrated SIG Recoil Dampening System (SRDS), the P385-MACH3D delivers ultra-flat tracking, faster sight recovery, and unprecedented control during high-speed firing sequences.

At the center of the platform is SIG's all-new modular Fire Control Unit (FCU), featuring a patented Flush-Faced Trigger Block design paired with a flat skeletonized trigger for a crisp break, minimal overtravel, and a highly tactile reset. Encased in a Nitron® finished stainless steel SIG-LOC PRO optic-ready slide with aggressive serrations, it comes equipped with factory XRAY3 Day/Night sights, an extended slide release, and a detachable magazine funnel for rapid reloads. Complete with laser-cut ReActive grip texturing, customizable MagStrap backstraps, and P320 magazine cross-compatibility, the P385-MACH3D ships with high-capacity steel magazines.
