I'm not a big fan of doubles, but I want a double so I can have 2 extra mags during a class.Raven makes GREAT mag pouches.
Myself, however...I'm not a fan of the doubles. They take up a lot of real estate.
My EDC, though, is a Blackhawk pouch. I've got 2 for my Shield and I've got 2 for my FS. I also have 1 or 2 Raven single mag pouches for the FS.
The blackhawks are NOT low profile, however.
I know a lot of people are quite happy with the Comptac mag pouches, too. Single Magazine Pouch Belt Clip | Accessory | Comp-Tac

This is what I have been using. They are not bulky and can place one next to the other with minimal space.
