Not bad. - Maxpedition Dual Mag Pouch Insert - Black 3503B

The back portion with the velcro bends a little with double stack mags or a Surefire G2L in it. That can cause the hook on the pouch to detach from the loop in the bag around the edges. Not a deal breaker though, I own three and they still do what they are meant to.
Pros: Well made
Cons: Back isn't as stiff as it could be.
