The Sig Sauer P320 10-round 9mm magazine is a reliable, factory-spec spare mag built for shooters who run the P320 Legion or carry the P320 in standard configurations. Whether you're stocking up for the range, building a rotation for duty or everyday carry, or simply keeping a backup on hand, this blued steel magazine delivers the dependability you expect from Sig Sauer's in-house ammunition and magazine line.
Constructed from steel with Henning Group aluminum basepads, these magazines are engineered to feed cleanly and withstand repeated loading cycles without losing tension or developing feed issues. The 10-round capacity works across P320 Carry and full-size variants—with or without a magwell—making it a versatile addition to any P320 platform setup.
If you shoot a P320, you know that spare magazines are wear items. Mags get dropped, loaded hard, and run through thousands of rounds over time. Having quality factory replacements in your kit means you're always ready, whether you're training for a match, preparing for a hunt, or maintaining your carry gun. This is the magazine Sig engineered for the Legion and standard P320 platform—no guessing, no adapter games.
