A preferred embodiment of a firearm cartridge clip is disclosed, in which the clip has an elongated housing extending from an open top end to an enclosed bottom end defining an elongated cartridge storage chamber. The clip has a cartridge support seat mounted in the chamber above a separate elevator element. A chamber compression spring is mounted in the chamber between a base at the bottom end and the elevator element to urge the elevator element upward. A separate movement-restraining means is associated with the cartridge support seat to resist downward movement of the seat from the opening at the top end. The clip has a loading facilitating means for selectively rendering the compression spring ineffective to urge the seat upward to thereby reduce the manual effort required to load the clip.
