The Sig Sauer P320 Grip Module X-Series in large size gives you a platform to build out a full-size, duty-ready 9mm, .40 S&W, or .357 Sig handgun. This black polymer grip module is the foundation of a P320 X-Series conversion—install your existing P320 firing control unit into this module and pair it with a compatible X-Series slide and barrel to transform your setup. It's designed for shooters who want the modularity the P320 platform is known for, with the refined ergonomics of the X-Series line.
This is a grip module assembly only, so you'll need to source the slide, barrel, and firing control unit separately. The large size fits shooters who prefer a full-size grip profile (4.70" overall on the pistol). One important note: these X-Series grip modules are compatible with magazines that carry the SIG Mark on the baseplate—not the older "SIG SAUER" text baseplate style. That's a detail worth double-checking if you're upgrading an existing P320 setup.
Whether you're a competition shooter dialing in the perfect P320 configuration, a duty officer looking to modernize your platform, or someone who values the flexibility of a truly modular system, this grip module is a solid building block. The black polymer construction is durable and field-proven, and swapping control units between modules means you can tailor caliber and configuration to your mission without buying a whole new gun.

Frequently Asked Questions
Will this grip module work with my existing P320 magazines?
Check your magazine baseplate. X-Series grip modules are compatible with magazines featuring the SIG Mark on the baseplate. If your magazines have the older "SIG SAUER" text on the baseplate, they are not compatible with this module.
What do I need to complete a P320 X-Series build with this grip module?
This is a grip module assembly only. You'll need a P320 firing control unit, a compatible X-Series slide, and a compatible X-Series barrel in your chosen caliber (9mm Luger, .40 S&W, or .357 Sig) to complete a functional pistol.
Does this grip module include the extended magwell and internal weight?
No. This grip module does not include the extended magwell or internal weight that come on some X-Series configurations. It is a base large-size module designed for modular customization.
What calibers can I build with this grip module?
This module is compatible with 9mm Luger, .40 S&W, and .357 Sig when paired with the appropriate X-Series slide and barrel assembly for your chosen caliber.
