I ordered this unloading tool and some moon clips for my S&W Performance Center 642. This was my first experience using moon clips. Loading the moon clips without any tools isn't too tough, as long as the ammunition is a decent fit for the clips (I never had any idea how much variation there was from one ammunition manufacturer to the next!). But unloading the spent cartridge casings from a moon clip proved to be a challenge. With my fingers I just couldn't seem to get a grip on the first one without torquing the clip in a way that felt like I was going to bend it. With this clip unloading tool, the rounds pop right out with a quick twist. They also drop neatly into the tube, which is convenient. The tool is definitely well made and should last forever. I also can't say enough about how great the customer service from TK Custom was. I will definitely be ordering from them again!
