The Blackhawk magazine pouch is a good alternative to other more expensive ones. Provides great magazine retention even while running and the slim profile allows to have multiple pouches without occupying too much real estate on the gun belt. I use mine for USPSA practical competition and the only gripe I have with them (which I solve with my trusty Dremel tool) is that they are unnecessarily too deep. The leaf spring that applies the pressure on the mag body for retention does a great job, thus no need for such a deep pouch body.
Pros: Compact & easy to set up
Cons: TOO DEEP
