This Sig Sauer Magazine is a Factory Original Replacement Part, manufactured to the same specifications and tolerances using the same materials as the OEM Magazine that came with the pistol, guaranteeing optimal fit and reliable operation. When it comes to semi-automatic firearms, the ammunition feeding device often determines if, and how well, the gun functions. Therefore, whether for use as a backup mag for your pistol, or simply to spend a little more time shooting and a little less time reloading on the next trip to the range, keeping a few spare factory magazines handy is never a bad idea.
This Sig Factory 1911 Magazine fits Sig Sauer Full Size 1911 variants as well as most other 1911 Government and Commander-sized pistols in 45 ACP. It will function in most Officer-sized 1911's as well but will extend below the grip frame. Stainless steel magazine body with a black polymer floorplate.
