Yes... full (6-shot) moon-clips really speed up ejection and reloading. I have half-clips, but rarely use them, they are slower. I suppose tactically, if you wanted to shoot 3 and top back up to 6, you might consider half-clips.
You load up as many as you need for range or carry use, for carry I might carry one, sometimes 2 loaded moon-clips. They are pretty sturdy, do not come apart in my pocket (like speed-loaders).
For loading, you just roll a 45 ACP cartridge into the clip, pushing it in. Its pretty easy. Getting them out is difficult, I use a small pair of cotter-pin pliers, very quick. Any set of long nose tipped pliers will work, just bring the plier tips to the bottom of the shell base before pulling off.
Congrats on your aquisition.
PS: Accuracy? Haven't noticed any difference between 3 or 6 shot moon-clips.
