Abstract: A cartridge loader receives a magazine. The loader directs a cartridge into the top of the magazine. A lever in the loader is pivoted to insert the cartridge while the lever simultaneously downwardly depresses existing cartridges in the magazine to make space for the cartridge being inserted in the top of the magazine.

Abstract: A revolver cartridge loader includes a plunger and a base. The plunger includes an array of circumferentially equally spaced cartridge engaging feet each including a distal end, includes a first aperture having a first diameter, and includes a second aperture operatively associated with the first aperture. The second aperture has an upper end and a lower end, and has a second diameter less than the first diameter. The base includes a plurality of circumferentially equally spaced openings each shaped and dimensioned to slidably receive a different one of the cartridge engaging feet. The base also includes an outwardly extending member integrally formed as a portion of the base. The outwardly extending member includes a resiliently compressible upper end shaped and dimensioned to compress resiliently to pass through the second aperture into the first aperture and, after passing through the second aperture, to expand into the first aperture to prevent the upper end from again passing through the second aperture.
