Overview
The Agency Arms +5 Magazine Extension (BP-320-BLK) is designed to enhance capacity and performance for full-size SIG Sauer P320 magazines. Precision-machined from 6061-T6 aluminum with a Type 3 hard-coat anodized black finish, this base pad increases magazine capacity by 5 rounds for 9mm (or 4 rounds for .40 S&W). It includes a chrome silicon alloy spring and features an extended ledge that facilitates smooth, one-handed manipulations—making it an ideal upgrade for competitive shooters and everyday carry setups alike. The base pad is equipped with a convenient dot matrix panel for marking and easy magazine identification. It is compatible with standard SIG Sauer factory magwells and Agency Arms X-Series magwells, though it is not compatible with the AXG magwell. This product is made in the USA.
