Built for shooters who demand reliability in their 1911 platform pistol, this Sig Sauer magazine delivers consistent feed with an 8-round capacity, perfectly suited for both full-size and carry variants of the classic .45 ACP. The steel construction and black finish provide durability and a professional look that matches most modern 1911 builds. Its compact footprint—measuring just under 10 inches in length—keeps the magazine trim without sacrificing capacity. The exchangeable base plate design allows for quick customization and makes cleaning or maintenance straightforward, while also enabling you to swap components if needed. This is the OEM magazine that Sig Sauer shooters choose for dependable performance in competition, duty, or everyday carry applications.
