doesn't it really depend on your current concealment method for your carry gun as well?
I mean, if you are wearing IWB, and have on say a long shirt, vest, or light jacket hanging over the gun... you can wear a OWN mag pouch and no one would notice.... hell, under that kind of wear and a small gun, your gun could be OWB as well.
BUT, if you are IWB and wearing a tucked shirt, so that your waist line and belt are showung.... a OWB mag pouch would look a bit out of place.
I think it's one of those things where you have a couple of each (get both!
so that you have ther versatility.
I am looking at having a IWB tuckable pouch made for me this month, when I get it (and the holster) I'll post pics. Reason I am looking for this is I wear a untucked shirt or a vest most times with my current IWB setup...but I want the OPTION to say go somewhere where being "untucked" would look sloppy, and not have to wear the vest....or if wearing a vest and/or jacket... have the option to remove without giving away my concealment.
