So does the 12ga hold 3" and 2 3/4" in the same caddy or are they specfic to length?
This is what I came up with with my SolCan shotshell (8) caddy.
Cheapo Condor chest rig, an admin pouch and a double STANAG mag pouch to hold a couple 6 shell cards.

Haven't got much use out of it yet but it feels like a good setup.
