The Sig Sauer MAG1911108 is a premium 8-round magazine purpose-built for full-size 10mm Auto 1911 pistols. If you're running a modern 10mm 1911—whether for hunting, competition, or serious defensive work—this stainless steel magazine delivers the capacity and reliability Sig Sauer's ammunition demands. The single-stack design maintains the slim profile that makes 1911s so shootable, while the robust steel construction and stainless finish handle hard use without complaint.
Built to Sig's exacting standards, this magazine features witness holes drilled into the side of the body so you can verify round count at a glance without fumbling or slowing down. The polymer baseplate absorbs impact and makes unloading smoother than bare metal alone. Eight rounds is a practical fighting load for the 10mm cartridge—plenty of energy downrange without unnecessary weight for most hunting and range applications.
If you own a full-size Sig 1911 chambered in 10mm, having at least one quality spare magazine isn't optional; it's maintenance. This one won't let you down.
