The SIG Sauer P385 is a new 9mm Luger, striker-fired pistol platform built around a dedicated Fire Control Unit, a grip-mounted SIG Recoil Dampening System and an adjustable MagStrap grip. Its feature set includes a low bore axis, SIG-LOC PRO optics mounting and compatibility with P320 magazines. The CARRY configuration pairs those features with a 4-inch barrel.
For concealed carriers, the most useful details are the size of the specific model, how its grip can be configured and which existing accessories will transfer. Here is what SIG’s published information establishes about the new platform.
Sig Sauer P385 CARRY and COMP specifications
The table below compares two specific configurations on SIG Sauer’s website. Magazine packages and other equipment vary by SKU.
| Specification | P385-CARRY | P385-COMP |
|---|---|---|
| SKU | 385CA-9-BXR3 | 385F-9-COMP |
| Caliber | 9mm Luger | 9mm Luger |
| Barrel length | 4 inches | 4 inches |
| Overall length | 7.22 inches | 7.9 inches |
| Overall width | 1.32 inches | 1.32 inches |
| Height | 5.64 inches | 5.64 inches |
| Weight with magazine | 28.94 ounces | 29.12 ounces |
| Included magazines | One 17-round and one 21-round | One 17-round and two 21-round |
| Iron sights | XRAY3 Day/Night | XRAY3 Day/Night |
| Optic mounting system | SIG-LOC PRO | SIG-LOC PRO |
| Factory-installed optic | No | No |
| Manual safety on this SKU | No | No |
Specifications for the SKUs shown.
Both listed configurations use a carbon-steel barrel, stainless-steel slide with a Nitron finish, polymer MagStrap grip module and M1913 accessory rail. Their flat triggers incorporate SIG’s Trigger Block. SIG specifies weight with a magazine; it does not identify these figures as loaded weights.
The model pages also list Coyote finishes, manual-safety options and versions supplied with 10-round magazines. The CARRY 10-round package includes two magazines; the COMP 10-round package includes three.
How the P385 manages recoil
SIG combines a low bore axis with its SIG Recoil Dampening System, abbreviated SRDS. The company places SRDS inside the grip module and describes its purpose as reducing the shock transferred to the shooter. SIG says the combined design improves controllability and sight recovery.
The P385-COMP adds compensation integrated into its slide. It retains a 4-inch barrel, while its listed overall length exceeds the CARRY’s. SIG attributes additional muzzle-rise reduction to that compensated slide. These are manufacturer performance claims; the specifications alone do not establish how either pistol will feel to an individual shooter.
The separate P385-MACH3D uses a MACH3D compensator, which SIG describes as employing additive manufacturing to direct propellant gases. It combines that compensator with SRDS and the platform’s low bore axis. This is a distinct configuration from the P385-COMP’s integrated slide compensation.
SIG advertises more than 30 percent less muzzle rise for the MACH3D compensator. That figure is a manufacturer claim about muzzle rise, not a measured percentage reduction in felt recoil for every P385.
A new FCU and flush Trigger Block
SIG developed the P385’s modular Fire Control Unit specifically for this platform. The new trigger architecture includes a Trigger Block that the company describes as an additional drop-safety mechanism. It stays flush with the trigger face and moves with the trigger during operation.
SIG’s stated objective is to incorporate that safety mechanism while preserving a smooth trigger feel, a defined break and a tactile reset. Those descriptions explain the design intent; they should not be read as a Concealed Nation trigger evaluation or independent safety certification.
MagStrap grip adjustment and controls
The MagStrap system gives the P385 two forms of grip adjustment: circumference and length. SIG lists small, medium and large fit options, along with the ability to change between grip lengths accommodating a flush 17-round or 15-round magazine. The company also describes its COMPACT configuration as using a compact MagStrap grip module.
That distinction matters when comparing configurations. Hand fit and grip length are separate considerations, and a magazine supplied with one SKU should not be assumed to describe every possible grip setup. Likewise, the existence of a fit option does not establish that every interchangeable component comes in every box.
SIG pairs the grip system with ReActive texturing and fully ambidextrous controls. The FULL model page also identifies textured thumb supports and a shielded slide release intended to reduce accidental interference with the control during use.
Which P385 models are listed
As of September 24, 2026, SIG labels P385-CARRY and P385-COMP as new. It labels P385-FULL, P385-COMPACT and P385-MACH3D as coming soon. Those website labels do not establish inventory at a particular dealer.
The FULL model is described as a full-size configuration with a 4.7-inch barrel. The COMPACT emphasizes a shorter grip configuration, while MACH3D adds the separately identified compensator. Exact equipment should be checked against the intended SKU.
Does the P385 use P320 magazines
Yes. SIG confirms P320 magazine compatibility, but says original round-basepad P320 magazines require removal of the P385’s metal magwell. Its compatibility list also includes the P320 AXG magwell and P-Series dovetailed iron sights; other components are platform-specific.
What optic footprint does the P385 use
SIG identifies the system as SIG-LOC PRO and states that it supports direct mounting of RMR and DPP footprints without an additional adapter plate. That does not make an optic-ready SKU an optic-included package.
Will P320 or P365 holsters fit the P385
No. SIG explicitly says the P385 is not compatible with P320 or P365 holsters. It calls for a holster designed specifically for the P385 to provide proper fit and retention. SIG names Safariland, ANR and BlackPoint among its initial holster providers.
Is the P385 replacing the P320
SIG says the P320 family, including the M17 and M18, will remain available and supported.
How much does the SIG Sauer P385 cost
The official platform and model pages reviewed do not provide an MSRP. A price therefore cannot be established from these sources. Confirm the exact model and current price with an authorized dealer.
For readers considering the P385, the next useful comparison is between the exact configurations they would actually carry: grip length, magazine package, sighting equipment and holster fit. The published specifications provide that starting point; range experience will be needed to assess the manufacturer’s shooting-performance claims.
