Upgrade your SIG SAUER® P320 with the Strike Industries P320 Aluminum Extended Magazine Plate and add up to +5 rounds of 9mm capacity without compromising reliability or handling. Precision-machined from rugged 6061-T6 aluminum, this extension is built to withstand hard use while maintaining a slim, low-profile design. Whether you’re competing on the clock, spending a full day at the range, or sharpening your defensive skills, extra capacity can make a real difference. Fewer magazine changes help you stay focused on shooting instead of stopping to reload. At the same time, the lightweight aluminum construction keeps your magazine balanced and easy to handle. This aluminum extended magazine plate features a streamlined, no-snag profile that promotes faster, smoother reloads. It slides cleanly into magazine pouches and seats confidently in your pistol. The added surface area also provides a more positive grip during reloads, helping you make quick magazine changes when every second counts. Designed to fit compatible 21-, 17-, and 15-round SIG SAUER® P320 9mm magazines, this extension is built with reliability in mind. It is also sized to meet USPSA dimensional requirements, making it a great option for competitive shooters who need additional capacity while remaining within match rules.
