The Sig Sauer P320 Grip Module X-Series Carry in small size gives your modular P320 platform a compact, carry-focused footprint without sacrificing shootability. This black polymer grip module accepts your existing P320 firing control unit and works with 3.90" and 4.70" slide-and-barrel assemblies in 9mm Luger, .40 S&W, or .357 Sig—making it a practical upgrade for shooters who want a shorter grip on their duty or defensive handgun. The X-Series Carry geometry is built around real-world carry ergonomics: a narrower profile, aggressive stippling for purchase in all conditions, and a frame design that balances concealability with control.
One of the smartest aspects of the P320 platform is its serialized chassis system. Your firing control unit—the regulated part—stays in your current grip module, and you swap the fire-control-bearing frame to change the gun's size, caliber, or configuration. This grip module lets you do exactly that, converting a full-size or compact P320 into a true carry gun without buying a whole new pistol. You'll need a compatible P320 slide and barrel in your chosen caliber; the grip module itself is the frame component.
Keep one detail in mind: this module does not include the extended magwell or internal weight found in some X-Series variants, and it is not compatible with magazines sporting the "SIG SAUER" text on the baseplate. Use magazines with the SIG Mark baseplates instead. If you're running a P320 and looking to downsize your carry gun or build a lighter, more concealable variant, this grip module gives you the modularity the platform was designed for.
