Abstract: A magazine for a firearm such as long guns comprises a housing defining a cavity for holding a double staggered stack of cartridges and spring-biased tiltable follower for dispensing the cartridges into the action of the firearm. Features include an accordion type flat spring specially configured to fold into a flat condition in which adjacent bends of the spring are arranged side-by-side to reduce the folded height of the spring. The follower includes bosses slideable in mating vertical housing slots to guide the follower upward/downward motion and allow front to rear tilting action. A coupling mechanism includes a plurality of interlocking mounting teeth forming a selectively interlocked arrangement for detachably assembling the floor plate to magazine housing. A resilient snap fit tab on the floor plate secures the coupling. The magazine is longitudinally elongated and configured to fit flushly with the underside of the firearm when mounted.
