I've gotten myself into a pickle, and while I know a little about guns I know nothing about revolvers. I purchased for my wife a ruger revolver, and it came with some Moon Clips. I used this to load the revolver. But I want to take out the loaded cartridges and moon clips. How do I do this on a Ruger? The tutorials that I'm seeing online show easy unloading when the cartridges are spent, but mine are not and attached to a moon clip. How can I remove all loaded cartridges including the moon clip holding them?
