The Coonan .357 Magnum Automatic is a unique 1911-style pistol engineered to reliably fire rimmed revolver cartridges like the .357 Magnum. Its design, originating from Dan Coonan's graduate project, overcomes the challenge of feeding rimmed rounds through an articulated magazine follower and a modified 1911 platform. Key differences from a standard 1911 include a longer ejection port, larger magazine well, pivoting trigger, and external extractor, with later models featuring a fixed cam barrel system.
