Any N-frame speedloader pouch that is not of the low-profile "belt-straddling" variety should hold two moonclips stacked atop each other. I'll do some digging and try and get you specific model names & numbers.
My DeSantis N-frame speedloader holder, which is of the belt-straddling type, will hold one, but you need to fish it out with a finger in the hole of the moonclip. I personally favor this, as a regular N-frame speedloader holder is of sufficient bulk that it's like having a small wastepaper basket strapped to your belt.
