Agency Arms Magazine Extension P320 +5 Ronin Red

The Agency Arms Magazine Extension for SIG P320 adds five rounds to your factory magazine capacity, extending your firepower without sacrificing reliability. Machined from 6061-T6 aluminum and finished in Ronin Red anodizing, this extension is designed for competitive shooters and those who carry full-size P320 pistols where legal capacity allows. The extended base pad provides additional grip surface for reload control and positive seating during high-volume shooting.

Installation requires disassembly of your existing magazine base plate and replacement with the Agency extension, along with the included magazine spring designed to maintain feeding reliability at the higher capacity. While the process is straightforward, care must be taken during reassembly to ensure proper spring tension and follower function. Test thoroughly with your carry ammunition before relying on extended magazines for defensive use.
