The beauty of the .45 ACP round in a revolver, using moon clips, is that you don't need $7 moon clips. You are buying nothing for the extra $6.60 per clip you would be spending over the Ranch Products clips (that's realistic as I believe that RP clips can be had for $40/100 - although it has been a while. The last ones I got were $35/100 and that is probably a lifetime supply). .45 ACP guns, with the short, fat, round nose heavy profile work well with a little jiggle in the clip. They literally self-align.
Just because they are inexpensive does not mean that RP clips are sub-par. They are high quality clips.
Don't get me wrong - there are guns and calibers where the $7 clips are absolutely needed in order to accomplish the fastest reload - fortunately, the .45 ACP guns aren't in that group.
Adios,

REMEMBER: The cost of the moon clip is directly proportional to the likelihood of the RO stepping on it.
