The Sig Sauer P320 10-round 9mm magazine is a steel OEM magazine purpose-built for full-size P320 pistols. If you carry or shoot a full-size P320 in 9mm Luger, this is the factory magazine spec you need—straightforward, reliable, and field-proven across thousands of P320 duty and civilian shooters. The double-stack design keeps the profile compact while maximizing round count, and the steel construction handles the abuse that comes with regular range use and daily carry.

The magazine features a polymer baseplate in coyote brown paired with the black steel body, giving it a purposeful, combat-ready look. Side witness holes let you verify your round count at a glance, so you always know what you're carrying into a match, the range, or the field. The steel tube and witness holes are engineered to the exacting standards Sig brings to all their P320 components—no flex, no surprises.

One critical compatibility note: these magazines are designed for full-size P320 frames only and are not compatible with the X5 grip module equipped with an extended magwell. If you run a standard P320 full-size, you're good. If you have the X5 or a compact grip module, verify your setup before adding to your cart. Like any quality mag, keep a spare or two on hand—it's the cheapest insurance against being short when you need to reload.
