This grip module assembly allows you to convert your P320 firing control unit into a full-size X-Series platform. It's a straightforward way to build or reconfigure your P320 without purchasing an entirely new pistol.
Installation Requirements: You'll need to install your existing P320 firing control unit into this grip module. You'll also need a compatible slide and barrel in your desired caliber.
Magazine Compatibility: This module works with SIG magazines that feature the SIG Mark on the baseplate. It is NOT compatible with older magazines marked "SIG SAUER" on the baseplate.
What's Not Included: This grip module does not include the extended magwell or internal weight system found on some X-Series variants.
The P320's modular design is one of its greatest strengths. This grip module lets you customize your platform to your exact specifications, whether you're building a competition gun, a duty weapon, or a personal defense firearm. The X-Series platform represents SIG's latest refinements in ergonomics and performance.
