Sig Sauer P320 X-Compact Grip Module Manual Safety 9/40/357 Polymer Black

The Sig Sauer P320 X-Compact Grip Module is a factory polymer grip frame assembly built for the modular P320 / M18 platform. Sized as the medium X-Series grip module with an integrated manual safety, this part accepts a Sig Sauer P320 fire control unit (sold separately) to configure a sub-compact carry pistol. The P320 FCU and slide are not included.

Chambering depends on the FCU installed. The grip module accepts Sig P320 fire control units chambered in 9mm Luger, 40 S&W, and 357 SIG, pairing with a 3.6" slide configuration to deliver the X-Compact carry footprint. Black polymer construction keeps carry weight light, while the X-Series grip geometry and standard grip texture provide a secure, ergonomic hold.

The integrated manual safety lever provides thumb-activated decocking for shooters who prefer a manual-safety-equipped configuration, mirroring the controls of the U.S. military-issue M18 service pistol. Whether assembling an X-Compact from a stripped FCU, swapping grip modules on an existing P320, or replacing a worn factory grip frame, this direct Sig Sauer part restores factory fit, feel, and function.
