What Are Moon Clips

Moon clip or moon clips are a circular piece of spring steel or stainless steel designed to hold a full cylinder of ammunition for a revolver together as a unit. Therefore, instead of loading one round at a time or using a speedloader, with a revolver moon clip, a full cylinder of ammunition can be loaded and the fired cases are all extracted together as a unit. Thus expediting the revolver loading and unloading process. Unlike a speedloader, a moon clip remains in the revolver during firing. TK Custom loading and unloading tools for the moon clips are recommended to assist the shooter with these administrative functions. A moon clip loader greatly speeds up the process of loading your moon clips. TK Custom™ carries a full line of competition products for Smith & Wesson as well as other popular manufacturers.
