How to use moon clips?

[zonker5]

My new 625 PC has square shoulders in the cylinder, and will head space off the rim just like a 1911. There is no recess in the cylinder, and the rim sits nearly as high off the face of the cylinder as when the moon clip is used, with ample room for a thumbnail. How tight the spent shell will be, I can't say. I haven't had it long enough to experiment. Replacing a fired shell is tight and won't fall out on its own, but not hard to remove either.

That might be nice in an emergency, but fast it is not.

I am confused...a 1911 head spaces off the case mouth and shoulder in the chamber, not off the rim.

The only way I can avoid occasionally writing that sort of thing is to walk away from what I've written then come back for a second proof read later. That does take some of the fun out of the forum. We know what he intended to write.
