SIG P385 Unveiled: 5 Models, P320 Mags, Price and Release Date

All five P385 models are 9mm, and four of them use a 4-inch barrel. The P385-FULL is the exception at 4.7 inches. The models differ in compensation, grip length, and how many magazines come in the box.

The P385-MACH3D carries SIG's MACH3D compensator, which SIG says cuts muzzle rise by more than 30%. The P385-COMP moves the compensation into the slide itself. The P385-COMPACT keeps the 4-inch barrel but pairs it with a shorter MAGSTRAP grip and 15-round magazines, giving it the shortest grip of the family.

The P385 is a new design built around a new fire control unit, rather than a P320 or P365 variant. SIG pairs the FCU with a patented SIG Trigger Block and describes the trigger press as smooth and clean.

The FCU sits in the new MAGSTRAP grip module, which SIG says adjusts for both grip length and hand size. Laser-cut ReActive texturing covers the grip. SIG also calls out an extremely low bore axis, a precision-cut carbon steel barrel, and the SIG Recoil Dampening System for a softer, flatter recoil impulse.

Fully ambidextrous controls come standard on every model. Buyers choose between a pistol with or without a manual thumb safety, in black or Coyote Brown.

The P385 uses the standard P320 magazine. SIG confirms this in its SIG NEXT material, so P320 owners can carry existing 17-round and 21-round magazines over to a full-size P385. The P385-COMPACT ships with 15-round magazines to match its shorter grip.

Magazines are the only shared part SIG has named. Holster fit, FCU swaps, and grip modules from the P320 upgrade ecosystem need their own P385-specific confirmation before you buy.

Every P385 slide is cut for SIG-LOC PRO, SIG's optic mounting system that fastens the sight from underneath the slide. SIG shows the P385 with its new XRAY5 Advanced Red Dot Sight, which is offered in SIG-LOC PRO and SIG-LOC COMPACT versions.

That pairing was visible before launch: SIG's XRAY5 FAQ material listed the P385 as a SIG-LOC PRO host in August. Our SIG XRAY5 report covers the sight's 225-dot digital zero and its LightFight pairing with the FOXTROT2R weapon light.

The P385 starts at $599 and reaches stores in fall and early winter 2026. The P385-MACH3D is slated for the end of 2026.

The launch closes a trail that started with a U.S. trademark filing in December 2025. A planning board that surfaced on r/SigSauer listed a September 24 launch; SIG's official SIG NEXT unveiling came on September 22.

No. The P320 and P365 stay in production. The P385 joins them as a third striker-fired family, sharing magazines with the P320 and drawing design cues from the P365.

For a P320 owner, the practical draw is the new FCU and trigger block with the magazines already on hand.

Six other pistols launched alongside the P385 at SIG NEXT 2026: the P211-FULL and P211-CARRY, the P365-MACH3D, the Custom Works P320 NIGHTSHIFT, the M17-SOF, and the P226X AGENCY built with Agency Arms. SIG's new optics, including the XRAY5 red dot and FOXTROT2R LightFight weapon light, are covered in our SIG XRAY5 and SIG NEXT optics report.
