Thank you for posting that photo. I, too, have not seen them. Heard good things about them but I have several hundred of the Ranch Products moonclips so no real need for more.
So, they appear thicker than metal but the rim fits in the recess so the thickness adds to the strength. Interesting. I can see why folks like them. Went to the website and there is a newer version that holds the rounds better.
Thanks again for the photograph.

Hey Kevin-I have arthritic hands. Small motor moves are a little difficult. Those clips are easy to load for me. There are two strengths. I have both. Not much different in function. I also have 929 clips from RIMZ. I shoot my 625 and 929 more since I found an easier (for me) way to load clips. PM me and I will send you a short video of loading them. Enjoy
