Availability: In Stock
The Sig Sauer Grip Module Assembly for P320/P250 is the core that transforms your modular Sig platform pistol into a compact carry or duty gun. If you already own a P320 or P250 firing control unit—the serialized heart of your pistol—this grip module lets you swap calibers and ergonomics without buying a whole new gun. It's one of the smartest moves for shooters who want flexibility: install your FCU, pair it with the matching slide and barrel in your chosen caliber, and you've got a fresh gun ready to go.
This module ships in medium grip size and is compatible with 9mm, .357 Sig, and .40 S&W when paired with the corresponding slide and barrel assemblies. The modular design is what makes the P320 and P250 platform so practical for duty, sport, and personal defense—you get a serialized frame once, then build around it. It's the kind of smart engineering that appeals to shooters who think long-term about their gear.
Whether you're running multiple calibers at the range, setting up a duty pistol alongside a compact carry gun, or just experimenting with different ergonomics, this grip module is the backbone of that flexibility. Condition and finish will vary with your specific module; verify compatibility with your slide, barrel, and FCU before assembly.
| Brand | Sig Sauer |
| Platform | P320/P250 |
| Grip Size | Medium |
| Compatible Calibers | 9mm, .357 Sig, .40 S&W |
| Requires | FCU (Firing Control Unit), matching slide and barrel |
You'll need a P320 or P250 firing control unit (the serialized component), plus a slide and barrel chambered in your desired caliber—9mm, .357 Sig, or .40 S&W. The grip module alone is the frame and lower assembly.
Yes, this grip module is caliber-agnostic. To change calibers, simply swap out the slide and barrel assembly for one in 9mm, .357 Sig, or .40 S&W while keeping the same FCU and grip module.
This grip module is designed for P320 and P250 firing control units. Verify your FCU and chosen slide/barrel combo before assembly.
This is a medium grip size, suitable for most hand sizes and offering a balance between control and concealability.
