Leaf springs for use in a firearm magazine are described. The leaf springs comprising an inner edge, an outer edge, and a channel, and configured to facilitate movement of cartridges within a feed tower of the firearm magazine. The leaf springs can be in a flexed or unflexed position, wherein downward movement of the cartridges in the feed tower outwardly flex the leaf springs into the flexed position to facilitate downward translation of the cartridges by forcing the inner edge of the leaf springs away from the cartridges, and in the unflexed position, the inner edge of the leaf springs is parallel or substantially parallel to an edge of the cartridges in the feed tower.

A double stack magazine for a firearm comprises a tubular magazine body defining a cavity for holding a stack of cartridges, a spring, and a follower biased by the spring for dispensing cartridges from the magazine. The cartridges may be rimmed cartridges in one embodiment arranged in a vertically staggered side-to-side arrangement. The magazine includes a lower double stack section and upper single stack section. The follower includes angled front and rear cartridge feed surfaces each configured to exclusively engage the cartridge stack at alternate times depending on whether cartridges are present in the lower double stack section. The magazine further includes a pair of non-linear cartridge convergence ribs configured to engage the cartridge stack and force the projectile ends thereof together in the upper single stack section to center an uppermost cartridge in the stack for dispensing from the magazine to the firearm for chambering.

A mechanical magazine, including a casing and a mechanical driver. The casing includes an ammunition inlet, an ammunition outlet, and an ammunition passage extending from the ammunition inlet to the ammunition outlet. The mechanical driver is disposed on one side of the casing and is configured to drive ammunition pills to move from the ammunition inlet to the ammunition outlet. The mechanical driver includes a rotation disc and an energy storage unit; the rotation disc is rotationally connected to the casing to push the ammunition pills to move along the ammunition passage; the energy storage unit is disposed on the rotation disc and is subjected to elastic deformation to store or release energy when the rotation disc rotates relative to the casing; when the rotation disc rotates in a direction towards the ammunition inlet, the energy storage unit is compressed to save energy.
