This pouch is incredibly good. It fits the mags perfectly. Put the mags in, which slide in easy, then strap the top flap on, and the mags are never coming out. The pouch holds tightly to your body too! Additionally, if you want to reload fast at the expense of holding the mags in super well, you can put the top flap into its mag holder, then put the mag on top. Then you don't have to unstrap the flap to grab a mag, and it holds in pretty well! (But not as good as with the strap on)
