Revolvers have a number of advantages over semi-automatic pistols, but speed of reloading is not one of them. Revolvers are limited by relatively small ammunition capacity, which is made even worse by the slow and sometimes difficult reloading process. Still yet, in a world full of high-capacity autoloaders, many lawfully armed citizens still choose to carry a revolver. Over the years, a number of different techniques have evolved to help load revolvers more quickly and reliably, including speed loaders, speed strips, and moon clips.
Of these techniques, however, the use of moon clips may be the least understood. Outside of revolver competitions, the use of moon clips is somewhat uncommon, but moon clips are a tool worthy of your consideration.
What are the advantages of moon clips? Moon clips are designed to increase the speed and reliability of loading a revolver. Unlike the function of a speedloader, the cartridges are never separated from the moon clip—all the rounds stay attached to each other and to the moon clip even when the revolver cylinder is closed for firing. The moon clip, however, also aids the reloading process. Traditional revolvers can have difficulty in reliably extracting spent cartridges.
What are the disadvantages of the moon clips? Moon clips do have a number of potential disadvantages that must also be considered. As a tactical matter, using moon clips limits your ability to perform partial reloads. Moon clips also have the potential to decrease the reliability of a revolver. Moon clips are stamped from relatively thin spring steel and can be bent or slightly warped by improper handling. A bent moon clip has the potential to jam a revolver by inhibiting the proper rotation of the cylinder.
