When you want more moonclips, Ranch Products is the original manufacturer of the modern moon clip (I believe). They produce the metal 1/2, 1/3, and full moon clip. Which one you will need depends on how you plan to use the revolver. I carried an ACP revolver when I wore a badge. In the cylinder I had 1/3 moons indexed so I could "tactically reload" after the first double tap. Good idea, but impractical in the field. I went to full moons and never looked back. 1/2 and 1/3 moons may have some benefit on the test range, keeping loads separate, but when I developed a load I charged the cylinder without clips and relied on gravity to drop the empties.
I never have tried the Rimz but several others whom I respect like them.
For a demoooner, there are three basic options.
Make your own from a length of thin wall tubing or golf club shaft. Buy one. Or, hook the empty in the corner of a metal ammo can, pull the clip away from the can, repeat until clip(s) are empty. All the empties are now in a nice covered can to carry home and reload.
Mooning tools are different but not hard to make. Study what is available for sale and build or buy as you see fit.
Congratulations, an ACP revolver is about the best there is to be had. I hope you enjoy yours. I have more than a few and prefer them to all others.
