Abstract
A restricted capacity cartridge magazine includes a magazine body having four walls defining a chamber for housing cartridges, a bottom end and an open end through which cartridges may exit and a follower assembly for moving cartridges through the chamber toward the open end. The follower assembly includes a follower body and a constant force spring unit. Blocking members formed in opposing side walls terminate at a slot forming opposing lips which extend a predetermined distance into the chamber to contact portions of the the lowermost cartridges in the magazine to limit the movement of cartridges away from the open end of the magazine. The constant force spring unit terminates at a length such that the magazine is disabled if the follower body is moved past a predetermined distance from the open end of the magazine.
