The Sig Sauer P320 Grip Module X-Series in Coyote is a modular frame assembly built for shooters who want to customize their P320 platform. This small-size grip module accepts your existing P320 firing control unit and lets you build a full-size X-Series handgun in 9mm Luger, .40 S&W, or .357 Sig—simply swap in the corresponding slide and barrel for your chosen caliber. It's the core of Sig's modular ecosystem: buy once, reconfigure for different roles.
The Coyote polymer construction is durable and professional without the bulk or weight of steel. The grip module itself measures 4.70 inches and is sized for a full-size P320 platform, providing the handling you expect from a duty or range gun. This is the bare frame—no magwell extension or internal weight is included, which means you get exactly what you need without paying for features you don't. It's a straightforward, no-frills path to P320 versatility.
Important: this grip module requires compatible P320 slide and barrel assemblies in your chosen caliber; it does not include them. Also note that X-Series grip modules work only with magazines featuring the SIG Mark on the baseplate, not the older "SIG SAUER" marked baseplates. If you already own a P320 firing control unit and have a slide/barrel set, this module unlocks a whole new build option.

Frequently Asked Questions
What do I need to use this grip module?
You'll need a P320 firing control unit (the serialized internal assembly) and a P320 slide and barrel chambered in 9mm Luger, .40 S&W, or .357 Sig. The grip module alone is the frame; it does not include firing control or caliber-specific barrel and slide components.
Is this grip module compatible with all P320 magazines?
No. X-Series grip modules work only with magazines that have the SIG Mark on the baseplate. They are not compatible with older "SIG SAUER" marked baseplates.
Does the X-Series grip module include a magwell extension or internal weight?
No. This module does not include an extended magwell or internal weight. It is a standard, lightweight frame assembly.
Can I switch this grip module between different calibers?
Yes, the grip module itself is caliber-agnostic. To change calibers, you swap the slide and barrel assembly while keeping your firing control unit and grip module the same.
