There are a number of options.
1) you can buy or make an unloading tool. I turned this piece of tubing on my lathe to cut both ends and then knurl it just be fancy. Then I ground the end off about 1/8” deep most of the way through so it left a tab about 3/16” wide. Then I cold blued the tube for rust protection and to make it look pretty.
The tab engages the edge of the moon clip and when you rotate the tube the round or case pops out and falls in the tube. With a rubber cap or finger over the end you can capture all the cases. There’s also a store bought version in the center of the next picture.
2) in this picture if you look at the end of the TKS moon clip loading tool you’ll see a flat piece of metal bent into a curved shape at the end with a notch on each side. It works the sa,e way. Hook the curved part around the round or case, and then lever the case out by twisting with the notch against the clip.
3) Speed Beez includes a tool w with their moon clips that works for 9mm/.38/.357 as well as .44/.45. They are plastic and don’t last forever but they are inexpensive. there’s another one in the picture above.

In terms of moon clips, quality matters. The only clips I bother with are the clips make by TK Customs or by Speed Beez. The only factory original to the revolver moon clips I have liked have been from Ruger, but quality on them is spotty.
Everything else I have come across is prone to bending.
