I'm 5'10" 165lbs. and I'm currently using CCC BMCs at 10:00. These are by far the most concealable mag carriers I've used. I previoulsy used Comp-Tac carriers but they print much more than the BMC. I also think the Raven carriers conceal well but they take up a lot of space on my belt compared to the BMC. The Kytex Gear carriers look good and are priced right but I've never personally used one.
