I bought a chest rig for a class I'm going to take. The class requires one. I use an AK so that's what I'm using it for. Here it is: My question centers on the magazine retention tabs. I'm talking about these: How do they retain mags when one side goes through loops and then just dangles in the mag pouch? The obvious thing to do would be to knot them together so they don't pull out when you pull the tab but I want to make sure this is what you are supposed to do.
