1. A magazine assembly for a firearm, the magazine assembly comprising:
an elongated housing comprising a proximal end and a distal end;
a spring positioned in an interior of the elongated housing;
a first plate removably engaged with the proximal end of the elongated housing;
a second plate configured to engage with the first plate and secure the first plate at the proximal end of the elongated housing;
at least one follower configured to move within the elongated housing based in part on a compression and decompression of the spring, and wherein the at least one follower is configured to support one or more cartridges;
one or more feedlips positioned at the distal end of the elongated housing, wherein the one or more feedlips are adapted to prevent upward movement of a topmost of the one or more cartridges until a bolt or slide chambers the topmost of the one or more cartridges, and wherein the topmost cartridge is in a single stack configuration, and wherein a centerline of the bolt or slide of the firearm is in a first plane; and
wherein a centerline of the topmost cartridge is in a second plane that is parallel to and laterally offset from the first plane such that the centerline of the topmost cartridge is arranged off-center from the centerline of the bolt or slide of the firearm so as to increase an engagement or overlap between the bolt or slide and the topmost cartridge.
