Abstract
A flat spring for firearm magazines has a one-piece unitary body with end half-coils at opposite ends and interior coils in a repeating arrangement between the end half-coils. Each of the interior coils includes an upper half-coil and a lower half-coil, each extending between outer tips on opposite sides of the spring body. Increasing and staggering the half-coil lengths, adjusting the radii of the outer tips and shaped matching the end half-coils and upper and lower half-coils within the magazine housing all contribute to a flat magazine spring that uses all available space within a firearm magazine to effectively reduce the number of coils and material thickness so that the compressed spring height is at its absolute minimum, thereby allowing for maximum space for ammunition.
