The Sig Sauer P320 Grip Module X-Series Carry in large size is the foundation piece for building or converting a carry-ready 9mm, .40 S&W, or .357 SIG pistol. If you own a P320 or P250 firing control unit, this modular grip lets you swap calibers and configurations without replacing the serialized fire control group—a smart way to expand your platform without the paperwork or expense. The black polymer construction is durable and ergonomic, designed to fit the full-size P320 frames (3.90" and 4.70" slide lengths) while maintaining the refined feel Sig built into the X-Series line.
This grip module assembly forms the backbone of your P320 build. Drop your existing FCU into this housing, pair it with the matching caliber-specific slide and barrel, and you've got a complete pistol. The large size module gives you a full-length grip ideal for shooters who prefer a substantial platform for duty, range work, or field carry. It's the modular simplicity that made the P320 famous: adapt your gun to your mission without swapping serialized parts.
One important note: this grip module does not include the extended magwell or internal weight found on some X-Series configurations. Magazine compatibility requires Sig baseplates marked with the SIG Mark only—mags bearing "SIG SAUER" text on the baseplate won't work with this module. Make sure you have the corresponding slide and barrel in your chosen caliber before ordering; this is the grip and frame portion only.
