Someone tell me how the moon clips in 38 special work, I used to have a 940 so I am familiar with now rimless moon clips work; they seem to keep the rounds together quite well. I was considering sending my 637-3 off to have the cylinder machined to accept moon clips but since I have never seen one like this I don't know what to expect. Since the 38 special round has a rim how does it (if it actually does) lock into the moon clip or do the rounds fall free. Would the moon clip be able to be carried loosly in a pocket as an extra reload or again are the rounds going to come loose.

Someone who has or uses one give me some advice. I am fast with a speed loader and quite quick with a speed loader but I feel the use of 38 special moon clips would make reloading under a stressful situation that much faster.

I want to get some more advice before I commit to getting it done.
