Sig Sauer
The Sig Sauer Mag 1911 9mm magazine is a 9-round single-stack mag purpose-built for full-size Sig Sauer 1911 pistols in 9mm Luger. If you've got one of Sig's 1911 9mm platforms and need a reliable spare mag or backup supply, this is the factory-spec magazine engineered to feed and function the way your pistol expects. Whether you're at the range, in competition, or carrying, reliable magazines are as critical as the gun itself—and this one is built to the standards Sig's reputation depends on.
Constructed from stainless steel with a polymer baseplate, this magazine handles the rigors of regular use and storage without sacrificing durability. The side witness holes let you visually confirm your round count at a glance, so you know exactly where you stand in a magazine change. Full-size dimensions match the 1911 platform perfectly, so there's no guessing about fit or function.
Sig Sauer sources magazines from trusted manufacturers and holds them to tight specifications, which means you get the performance and reliability Sig owners expect. If you shoot a 1911 in 9mm, grabbing a spare mag or two is practical logic—you'll eventually want them, whether you're building a range kit or keeping backups in rotation.
