I use the WAS double mag pouches and they are great. They are elasticated on the sides so even when there is only one mag inserted it doesn't bounce around. I have recently picked up these which I believe are a clone of an Emerson gear pouch. They work like taco pouches but are made of rubber so they grip the mag very well. I've found they're more secure than a regular taco from testing at home but I haven't had a chance to test them in game
