You can't go wrong with this little pouch. It pancakes nicely against your body while holding your spare Glock magazine securely. The low-profile of the pouch is what sold me. So many other magazine pouches clip to your belt, and protrude an uncomfortable amount for concealment. Since you have to run your belt through the hoops, which spring out from the center of the pouch, this gets sucked up against you nicely, and nobody ever knows it's there. The retention is not super-strong, but I haven't had a mag fall out ever, and I don't think it will. Hand it to Glock to come up with a minimalist design that works better than so many others, while also being cheaper than them all. Love it.
