Springfield Armory PI4521 1911 45 ACP 10rd Single Stack Stainless Steel Magazine

The Springfield Armory PI4521 is a factory original 10-round single-stack magazine built specifically for the 1911 platform in .45 ACP. Machined from stainless steel with a bright natural silver finish, this detachable box magazine feeds reliably in full-size Government and Commander length 1911 pistols and uses a flush-fitting baseplate to maintain the pistol's original carry profile.

Built as a direct OEM replacement for Springfield Armory 1911 pistols, the PI4521 carries a 10-round capacity in the classic single-stack .45 ACP footprint. The all-stainless steel body provides excellent corrosion resistance and long service life, while the polished silver surface matches the factory stainless slides offered across the Springfield 1911 line.

As a true Springfield Armory part, brand-fit for the company's 1911 family, the PI4521 is the factory-spec spare for your full-size .45 ACP Springfield 1911 - ideal for daily carry, range rotation, or as a backup magazine.
