Magazine Sprgfld 45acp

The Springfield Armory Magazine for .45 ACP is a factory-original magazine engineered for the full-size 1911 Government and Commander platforms. Built to the same exacting standards as the firearms themselves, this single-stack magazine delivers the reliability operators and competitive shooters depend on during high-round-count range sessions and duty applications. The .45 ACP round's relatively low pressure curve means feeding reliability depends heavily on precise spring tension and follower geometry—Springfield's factory magazines account for both.

Dimensionally, the magazine measures 4.5 inches in length with a 1.8-inch width and 0.5-inch depth, fitting the standard Government-length 1911 frame profile without protrusion or rattle. The lightweight construction at 0.19 lbs per unit keeps carry weight minimal, a critical factor for those running multiple magazines on duty belt or range bag. Factory-grade components and precise manufacturing tolerances ensure consistent feeding cycles across hollow-point defensive loads, full-metal-jacket target ammunition, and +P variants—critical for duty weapons that must perform across ammunition types without tuning or break-in periods.

This magazine is purpose-built for 1911 operators carrying Government-size or Commander-size platforms in law enforcement, civilian concealed carry, competition, or training roles. Single-stack .45 ACP magazines are foundational to any 1911 system—most shooters maintain backup magazines to account for spring wear over thousands of rounds. Springfield factory magazines remain the baseline standard for 1911 reliability, offering the same fit and function as magazines shipped with new firearms.

Compatibility with aftermarket 1911 components varies by manufacturer tolerances. Verify frame fit before committing to high-round-count sessions. Storage in a magazine loader between shooting periods extends spring life and reduces fatigue—a best practice for any single-stack magazine kept in rotation.
