Sig Sauer P320, P320X & P250 Magazine Base Plates
Browse Sig Sauer P320 magazine base plates, also called floor plates or base pads, including options for P320X and P250 models. Compare NDZ standard and extended profiles alongside OEM Sig Sauer replacements and Ghost base plates. The selection includes aluminum and heavyweight brass NDZ designs, with different finishes and optional laser engraving on select products.
Choosing a P320 Magazine Base Plate
For a standard replacement profile, the NDZ P320 and P250 aluminum base plate replaces the factory floor plate without increasing magazine capacity. For a setup with a magwell, explore the NDZ Competition Pro Series extended plate, which is designed for use with a magwell. Heavyweight brass versions provide another material and weight choice. Confirm compatibility with your particular magazine, grip module, and magwell before ordering.
Match the listing to your caliber and magazine configuration rather than choosing by pistol name alone. For example, the standard NDZ aluminum plate linked above lists 9mm, .40 S&W, and .357 SIG applications and excludes .45 ACP models. An extended profile does not automatically mean added ammunition capacity; look for an explicit capacity specification on the product listing.
(*LZ) means that this product is capable of being laser engraved for personalization.
FAQs
Replacement base plates let you choose a different material, profile, finish, or personalized design. This category includes standard-profile replacements and extended designs, with aluminum and heavyweight brass options across the NDZ range.
Fitment varies by product. The standard NDZ aluminum plate linked above lists P320 and P250 applications in 9mm, .40 S&W, and .357 SIG, including X-Series models, and excludes .45 ACP. Competition Pro Series listings identify P320, P320X, and XFIVE Legion applications. Match the individual listing to your magazine and grip configuration.
The standard NDZ P320/P250 aluminum replacement plate retains factory magazine capacity. “Extended” can describe the plate’s external profile rather than additional rounds. Only treat a product as a capacity extension when its listing explicitly specifies an increase.
Install steps vary by part. NDZ recommends having parts installed by a certified armorer or qualified gunsmith.
Yes. Select NDZ magazine base plates offer different finishes and optional laser engraving. Products marked (*LZ) support personalization; available finishes and image choices are shown on the individual product page.
