A friend at the Agressor Group got this lil guy my way. The design is reverse flap style so one can get the flap out of their way and to the business and grabbing the mag easier. It can fit a single or double stack mag, but the elastic is a smidgn' tight on a double. Nothing drastic, but more than my other pistol mags.
There isn't a lot of velcro to seal the flap on your mag, but it is enough to be secure. I'm always eager to get into open flap mode anyway, and since the flap has velcro on both sides, it sticks nicely to the pouch to stay open. The back has PALS webbing to use a short Malice clip and a grommet is standard for drainage. For improvements, I'd like the hook velcro to be under the pull tab so one can open the pouch and secure the flap down all in one smooth motion. As is, one needs to pull down the flap to open, then let go to press the flap to the pouch. Other than that, if you like the reverse flap style, this is a well made mag pouch.
