The Sig Sauer Mag P320 9mm 10-round magazine is a reliable, purpose-built capacity option for your full-size P320 pistol. Built with a steel body and durable aluminum baseplate, this magazine combines practical capacity with the kind of durability you'd expect from Sig's factory ammunition. Whether you're building out your duty loadout, adding spares for the range, or keeping a backup on hand, a 10-round double-stack magazine offers a solid middle ground between full capacity and compliance-friendly alternatives.
The magazine features side witness holes so you can quickly verify rounds at a glance without removing it from the mag well. The full-size P320 platform is Sig's workhorse—trusted by military and law enforcement—and this magazine is engineered to feed and function flawlessly in that proven frame. The aluminum baseplate resists corrosion and handles the repetitive stress of loading, unloading, and range use without complaint.
Whether you're stocking spares for duty carry, match prep, or everyday training, having multiple magazines on hand is smart practice. Factory Sig mags ensure proper feeding and reliability without the guesswork of third-party options.

This is a full-size P320 magazine. While Sig magazines are often cross-compatible within the P320 platform, we recommend confirming fit with your specific frame size before relying on it for carry or duty use.
This magazine holds 10 rounds instead of the larger capacity available in full-size mags. The 10-round capacity makes it a practical option for states or departments with magazine limits, or for shooters who prefer a lower-profile setup.
Yes—the baseplate is removable for field-stripping and cleaning. After heavy range sessions, you can disassemble it to remove dirt, brass shavings, or debris that accumulates inside.
This magazine is listed as compatible with both P320 and P250 models, though we recommend a function check with your specific pistol to confirm reliable feeding.
