Description
This is the factory-standard grip module for the P320 Carry, made from durable black polymer that's built to withstand real-world use. If you're running a manual safety fire control unit (FCU) and want the classic Carry-sized grip profile, this module is the direct replacement Sig makes for the job.
Carry Profile with Medium Grip Size
The medium grip hits that sweet spot for most shooters. It's not as chunky as the full-size frame, but gives you more to hold onto compared to the compact. The carry profile specifically pairs a compact-length slide with a full-size grip, which a lot of people prefer for the balance between concealable package and shootability. You'll still maintain solid control without the added bulk of a full-size module.
Factory-Original Polymer Construction
Sig engineered these modules from quality polymer designed to last. The black finish matches all standard P320 factory slides, and since it's the OEM part, it's spec'd to work seamlessly with your existing setup. This isn't an upgrade piece with extra stippling or fancy materials. It's straightforward, reliable engineering that does exactly what it's supposed to do.
Universal P320 Compatibility
As long as you have a 9mm, .40 S&W, or .357 SIG manual safety FCU, this module will accept it. Drop your fire control unit in, and you're done. The installation is simple enough to do at home without any special tools, though some prefer to have a gunsmith handle it. Multiple sources confirm owners have successfully swapped these modules as part of building different P320 variations.
