Description
The Sig Sauer P320 Carry grip module with manual safety is a factory-original frame assembly designed specifically for users building or customizing their P320 platforms. This module ships in large circumference sizing and black polymer finish, making it compatible with any P320 firing control unit (FCU) that features the manual safety configuration. Simply drop your existing FCU into the module, attach your preferred slide and barrel assembly, and you're ready to go.
Large Carry Grip Geometry
This P320 grip module accommodates the full-sized Carry profile, which bridges the gap between compact and full-size builds. The larger grip circumference provides better control and a more substantial feel in the hand without the footprint of a standard full-size frame. The manual safety cut means this module works exclusively with P320 manual safety firing control units for secure, consistent operation. The black polymer construction is durable enough for daily carry or range use while keeping weight low.
Caliber Flexibility and Installation
This module pairs with 9mm, .40 S&W, or .357 SIG P320 slide and barrel combinations, giving you flexibility to build configurations that match your needs. Installation requires no gunsmith or special tools—just remove your current slide and takedown lever, drop in your FCU, then secure everything with the takedown lever. The design takes minutes to swap, so experimenting with different configurations is straightforward. You maintain complete control over your build by choosing compatible slides, barrels, and magazines independently.
Why Choose Factory Modules
Sig's factory grip modules meet the same standards as their complete pistols and offer straightforward compatibility without surprises. Unlike aftermarket options with different ergonomics or proprietary features, this module keeps your P320 true to the original design. It's perfect for builders who want reliable factory quality, users upgrading from standard modules to the larger carry size, or anyone looking for a proven replacement frame.

Frequently Asked Questions
What do I need to complete a P320 build with this grip module?
This module houses your firing control unit (FCU) only. You'll need a P320 manual safety FCU, a compatible slide assembly, and a matching barrel to complete a functional pistol. Magazines are sold separately. The FCU is the serialized component, so no FFL transfer is required for the grip module itself.
Is this grip module compatible with my current P320 gun?
This module works with any P320 manual safety FCU across 9mm, .40 S&W, or .357 SIG. If your pistol has a manual safety lever on the FCU, you can swap modules without tools. If your current gun has a trigger-only safety (no lever), this module won't be compatible since the manual safety cutout won't align with your FCU.
How does the large carry size compare to other P320 grip options?
The large carry module offers a noticeably bigger circumference than medium or small sizes, ideal for shooters with larger hands seeking a more comfortable grip. It's still more compact than a full-size frame, making it a practical middle ground for concealed carry or general shooting. The manual safety configuration means it only works with FCUs featuring the manual safety mechanism.
Can I use this module with different calibers?
Yes, this module is compatible with 9mm, .40 S&W, and .357 SIG configurations. You can swap in any compatible FCU and slide assembly for the caliber you want to shoot without changing the grip module. Magazine compatibility and barrel length depend on your specific slide choice.
