[Discussion] SIG Sauer Unveils Five-Model P385 Family of Modular 9mm Pistols

SIG Sauer Introduces P385 Pistol Family

SIG Sauer unveiled the P385, a new family of modular, striker-fired 9mm pistols, at its SIG NEXT event on September 22. The lineup consists of the P385-CARRY, P385-COMP, P385-FULL, P385-COMPACT, and P385-MACH3D.

The P385 is a separate platform rather than another P320 configuration. It uses a new serialized fire-control unit, interchangeable slides and barrels, and a grip module incorporating SIG’s recoil-dampening system.

SIG previously indicated that the Carry and Comp would lead the rollout, with availability expected during the fall and early winter. Its product listings currently mark all five models as “coming soon.” Firm shipping dates and suggested retail prices have not been announced. SIG also plans compliant versions for states with additional requirements.

Carry and Comp Specifications

The P385-CARRY has a 4-inch barrel, an overall length of 7.22 inches, and a listed weight of 28.94 ounces with a magazine. Standard versions include one 17-round and one 21-round magazine.

The P385-COMP also uses a 4-inch barrel but adds an integrally compensated slide. It measures 7.9 inches overall and weighs 29.12 ounces with a magazine. Standard configurations ship with one 17-round and two 21-round magazines.

SIG lists 10-round configurations, optional manual safeties, and black or coyote finishes. Specifications and release details for the Full, Compact, and MACH3D versions remain limited. The company says the MACH3D compensator reduces muzzle rise by more than 30 percent, though that performance claim has not been independently verified here.

New Modular Grip and FCU

The removable P385 fire-control unit is specific to the platform. SIG’s interchangeable Magstrap system adjusts grip length, circumference, and trigger reach without replacing the complete grip module. It can also convert the same module between full-size and compact grip lengths.

Available Magstrap circumferences are listed as 1.95 inches for small, 2.15 inches for medium, and 2.25 inches for large. Approximate trigger reach is 2.9 inches, depending on the installed Magstrap. The grip also uses SIG’s laser-cut ReActive texture.

Controls are fully ambidextrous, including the slide catch, magazine catch, and optional manual thumb safety. A shielded slide catch is intended to reduce unintended activation during handling or firing.

Recoil and Safety Systems

The P385 places the bore lower relative to the shooter’s hand and incorporates the SIG Recoil Dampening System in the grip module. SIG says SRDS absorbs vibration and works with the low bore axis to reduce felt recoil, muzzle movement, and sight-recovery time. Compensated variants add further recoil mitigation.

A new Trigger Block sits flush with the trigger face instead of protruding like a conventional trigger-safety tab. SIG describes it as a redundant drop-safety mechanism and says the P385 meets applicable commercial, professional, military, and law-enforcement testing requirements. These manufacturer claims have not been independently tested here.

Magazines, Optics and Parts Compatibility

The P385 accepts standard P320 magazines. Older P320 magazines with rounded basepads also work, but the P385’s metal magwell must first be removed. The P320 AXG magwell and P-Series dovetail iron sights are compatible; other P320 and P365 components are not.

All five models use the SIG-LOC PRO optic-mounting system, which directly accepts Trijicon RMR- and Leupold DeltaPoint Pro-pattern optics without an adapter plate. Base configurations use XRAY3 day/night sights.

P320 and P365 holsters do not fit the P385. SIG identifies Safariland, ANR, and BlackPoint among the companies offering initial P385-specific holsters. No calibers beyond 9mm have been announced, while SIG says the P320 family will remain available.
