This is an old post. However, I have noticed in most posts regarding the plastic moon clips, that there is no mention of the fact that there are TWO different types of RIMZ clips (EZ Moonclips). One is a flexible polymer that works fine for range use but doesn't retain the cartridges if a loaded clip is dropped. It is real easy to load without tools and lasts VERY well.
The latest material (they carry both models) is Hydrocarbon/Polymer. It is MUCH stiffer, will retain the cartridges when dropped, and still loads without tools. They also last a long time (I have yet to have one fail). The HCP is my recommendation. I have tools for steel clips but, frankly, they are a pain in the tuckus to load and unload. They can bend which renders them useless and they can rust.
If I was in World Class competitive shooting (I'm not shooting competitition these days) I "might" change my mind, but I REALLY like the RIMZ clips.
I would suggest you call to order, and have your EXACT model of revolver in front of you so they can get the right clip for your needs. In addition to the two different materials available, there are different models for different revolvers. Another thing, they are currently $31.50 for fifteen clips (including shipping) and that is not much money to try.
I have no connection to the firm making them but am a happy customer.
FWIW
