Sig Sauer
The SIG SAUER P320 .45 ACP Medium Black Grip Assembly is the frame and grip module foundation for building or customizing your P320 platform pistol. If you're looking to swap calibers, adjust ergonomics, or rebuild a P320 in .45 ACP, this genuine SIG grip assembly is the core component you need. It's designed for shooters who want modularity without compromise—whether you're a competitive shooter optimizing setup, a concealed carry user fine-tuning fit, or a range enthusiast experimenting with different configurations.
SIG's modular P320 platform is built around interchangeable grip modules, which means you can move your fire control unit between different frame sizes and caliber combinations. This medium-frame assembly in black comes ready to accept your P320 trigger group and slide. The medium frame strikes a balance between capacity and concealability—a sensible choice for most hand sizes and use cases.
Whether you're building a complete pistol from parts or swapping your grip module to match a new slide assembly or caliber, this is genuine SIG hardware engineered to the same standard as factory pistols. No workarounds, no proprietary fitment headaches—just straightforward P320 modularity.

Yes, this medium grip module is compatible with standard P320 fire control units and slide assemblies. The modularity of the P320 platform allows you to swap components as long as they're designed for the same platform generation.
The medium frame is designed as an all-around option for most shooters, offering a balance between capacity and handling. Frame size affects magazine capacity, grip circumference, and overall dimensions. We carry the medium frame here; verify your intended slide length to ensure proper fit.
A grip assembly is the frame foundation. To build a functional pistol, you'll also need a fire control unit (trigger assembly) and a slide assembly. Those components are purchased separately and then assembled into this grip module.
This is the grip assembly only—the frame and grip module. It does not include the slide, barrel, fire control unit, or any other internal components. It's the platform that those parts attach to.
