Sig Sauer 9/40/357 Carry Small Grip Module, Coyote

The Sig Sauer 9/40/357 Carry Small Grip Module in Coyote is the platform piece that turns your P320 modular system into a compact, duty-ready handgun. If you already own a P320 MS firing control unit, this grip module lets you swap calibers and frame sizes without buying a whole new gun—install your FCU into this module, pair it with the matching slide and barrel in 9mm Luger, .40 S&W, or .357 SIG, and you're done. It's the modular efficiency the P320 platform was built for, and it's built for shooters who want one gun that adapts to their needs.

The small grip frame fits shooters who prefer a more compact feel or those carrying concealed who need a tighter package. The Coyote finish is a tough tan that resists corrosion and pairs cleanly with modern tactical setups. This module is specifically designed for firing control groups equipped with a manual safety, so make sure your FCU has that safety lever before ordering.

Whether you're a competitive shooter building multiple uppers, a duty carrier who wants caliber flexibility, or someone who just appreciates the P320's modular design, this grip module is the foundation of that versatility. Pair it with the right slide and barrel assembly, drop in your FCU, and you've got a completely new gun configuration.

Frequently Asked Questions

Is this grip module compatible with all P320 firing control units?

No. This module is designed specifically for P320 MS firing control units equipped with a manual safety. If your FCU has a manual safety, you're good; if it doesn't, this isn't the right module for you.

What do I need to complete a functional P320 Carry with this grip module?

You'll need a P320 MS firing control unit with manual safety and a matching slide and barrel chambered in 9mm Luger, .40 S&W, or .357 SIG. The grip module alone is the frame; the slide, barrel, and FCU complete the firearm.

Can I use this to convert between calibers?

Yes. The modular design allows you to swap slides and barrels in different calibers while keeping the same grip module and firing control unit, as long as you use slides and barrels chambered in 9mm Luger, .40 S&W, or .357 SIG.
