Sig Sauer
Keep shooting longer between reloads with a Sig Sauer Magazine built to the same factory standards as the one that came with your P320, P320 X-FIVE, M17, or P250 full-size pistol. Available in 21-round or 30-round capacities, these 9mm steel magazines deliver the reliability you expect from Sig—no compromises on function or durability, whether you're training at the range, competing, or preparing for self-defense.
These aren't typical extended magazines cobbled together by a third party. Sig manufactures them with complete steel construction and a high-lubricity finish to ensure smooth feeding and consistent performance across thousands of rounds. The 30-round variant includes a removable sleeve that slides onto the base plate, giving you better ergonomics and grip comfort when you're running the magazine in your full-size grip module—take it off if you want a slimmer profile or prefer the bare magazine.
Maintenance is straightforward: the base plate is removable for quick cleaning and spring inspection. Witness holes marked in increments of five let you see your round count at a glance, so you know when to top off before a stage or training session. The high-tensile spring is engineered for long service life and consistent feeding under real-world use—no babying required.
Whether you're building out a competition setup, stocking spares for duty carry, or just want more time on target, these Sig factory magazines give you confidence that your ammo will feed when it needs to.
