12. A method as set forth in claim 1 wherein the cartridge driver reduces incremental travel of the plunger per unit movement of the actuator as the plunger approaches the magazine well.

13. A method as set forth in claim 1 wherein the plunger cradles the second cartridge for centering the second cartridge for introduction to the mouth end of the magazine.

14. A method as set forth in claim 13 wherein the plunger cradles the second cartridge by receiving the second cartridge in a valley in the plunger sized for at least partially receiving the second cartridge therein.

15. A method as set forth in claim 13 wherein the plunger cradles the second cartridge by receiving at least a portion of the second cartridge between first and second braces of the plunger.

16. A method as set forth in claim 15 wherein the braces move against a spring bias to a retracted position to cradle the second cartridge.

17. A method as set forth in claim 1 further comprising engaging a circumferential groove of the second cartridge with a cartridge retainer to limit movement of the second cartridge on the plunger.

18. A method as set forth in claim 17 wherein engaging the circumferential groove of the second cartridge with the cartridge retainer comprises moving the cartridge retainer to a retracted position against a spring bias.

19. A method as set forth in claim 1 wherein the handgun magazine includes a front wall, and wherein moving the plunger along the reciprocating path in the plunging stroke comprises pushing the second cartridge with the plunger in the first direction partially into the mouth end such that the second cartridge extends inboard of the front wall but not fully inboard of the front wall, and wherein operating the cartridge driver to push the second cartridge in the second direction comprises pushing the second cartridge in the second direction fully inboard of the front wall.
