context_page_description: A moon clip is a ring-shaped or star-shaped piece of metal designed to hold multiple cartridges together as a unit, for simultaneous insertion and extraction from a revolver cylinder. Moon clips may either hold an entire cylinder's worth of cartridges together, half a cylinder, or just two neighboring cartridges. The two-cartridge moon clips can be used for those revolvers that have an odd number of loading chambers such as five or seven and also for those revolvers that allow a shooter to mix both rimless and rimmed types of cartridges in one loading of the same cylinder.
  Moon clips can be used either to chamber rimless cartridges in a double-action revolver, or to chamber multiple rimmed cartridges simultaneously. Moon clips are generally made from spring grade steel, although plastic versions have also been produced. Unlike a speedloader, a moon clip remains in place during firing, and after firing, is used to extract the empty cartridge cases.
