I carry concealed and I use an IWB holster. I would like to find a good mag or double mag pouch that stays close to the body. My carry piece is a XD45C and I carry with the 10rd mags. Thanks in advance.
A double is probably less likely to "flop over," but singles can be positioned to conform better to your body.
I like a lot of brands, but Comp-Tac's mag carriers are especially good for concealed carry. They ride slightly lower on the belt than most, so the part that is below the belt keeps them from "flopping outward" if your mags are prone to do so (which is more likely with heavy, double stack mags), but they are not so low as to compromise concealment.
Honestly, I like the Fobus single mag pouch. I use it daily and it conceals well, holds the mag well and is easy on and off while still easy to draw from.
raven concealment. blade-tech or comp-tac are both fine. you might also try one of the leather doubles with the pouches turned inside your belt. old school, but works.
