Sig Sauer MAG1911458 1911 45 ACP 8-Rd Stainless Steel Detachable Magazine

The Sig Sauer MAG1911458 is a factory detachable magazine purpose-built for Sig Sauer 1911 pistols chambered in 45 ACP. This 8-round single-stack magazine is constructed from stainless steel with a silver finish, giving it the corrosion resistance and weight that serious 1911 shooters expect from a factory original.

Designed as a direct replacement for the magazine that ships with Sig Sauer 1911 pistols, the MAG1911458 fits the full-size Government, Carry, and Commander length 1911 platforms. An exchangeable floor plate is included, allowing easy disassembly for routine cleaning and maintenance of the magazine spring and follower.

Whether you need a spare for the range, a replacement for a worn magazine, or simply want a factory-original 45 ACP magazine for your Sig Sauer 1911, the MAG1911458 delivers the fit, finish, and reliability expected from a Sig Sauer factory accessory.
