I've been looking for inexpensive mag pouches for IDPA/USPSA, so I started with a Blade-Tech Kydex single mag pouch from Old School. I wanted some double mag pouches, but they're pretty expensive so I held off. Then two weeks later someone here linked to a special from Blade-Tech for injection molded (plastic) double mag pouches with Tek-Lock for $15 each.
I received the mag pouches today, and I really like them especially for the price. They are quality pouches, and the only real difference I notice compared to my Kydex mag pouch is that the Kydex pouch is slightly slicker inside. As an added bonus the leadtime was only 2 weeks from order to receipt, which is good considering Blade-tech says it may be up to 6 weeks on their kydex orders.
