Sig Sauer 1911 Officer Compact .45 ACP 7-Round Stainless Steel Magazine

The Sig Sauer 1911 Officer Compact .45 ACP 7-round stainless steel magazine is a factory-specification replacement or spare mag for shooters running Sig's Compact and Ultra compact 1911 platforms. Whether you carry one as your primary or keep backups on the range, a proper-fitting, reliable magazine is non-negotiable—it's the link between you and your pistol. This stainless steel magazine delivers the capacity and durability you expect from Sig's 1911 line without the fuss.

Built to Sig's exact standards, this magazine feeds .45 ACP reliably through the tight ergonomics of a 1911 Compact frame. Seven rounds give you practical capacity for a short-barreled carry or duty gun while keeping the footprint manageable. Stainless construction resists corrosion and wears well whether you're in the safe, the range bag, or the holster. Because Sig sources these from multiple trusted manufacturers to their specs, minor variations in finish and stamping can occur—but function and fit are held to standard.

If you shoot a Sig 1911 Compact or Ultra, having at least one spare mag on hand is smart practice. Magazines wear out, get lost, or simply need rotation to stay fresh. This is the OEM-spec part that goes in your gun and stays there.
