I run the orriginal style Choate Machine and Tool 6 round shell caddies. The CCW holders are made for 3" shells and need a real big spacer or the shells fall out, but they come with it. The Choates are made for 2 3/4" shells. I haven't found anything better for me, and believe me I have been given all of them to try and hopefully endorse and I still end up at the orriginal Choate 6 rounder, BUT....that is just for me, some guys just can't get used to grabbing 4 shells out of a 6 round holder so take all of this for what it is worth.
