A quick-release magazine for use with firearms is provided, the magazine comprising a conventional firearm magazine and a spring, the spring comprising a center plate with two fins projecting outwardly from the plate. The spring is positioned between the floor plate and base pad of the magazine, with the center plate of the spring aligning with the magazine and the fins projecting outwardly from the plate. When the magazine of the present invention is inserted into a firearm, the fins are compressed between the magazine and the gun. The compressed fins provide a forceful ejection from the firearm when the magazine must be replaced.
