I've always been worried that keeping my clips fully loaded is bad on the clips themselves. On my XD, I have the standard clip and the extended clip, and I don't keep them fully loaded, especially the standard clip that is my "backup" and is stored in my gun safe. My Keltech and shotgun, I'm not worried about since they are cheap guns, but in my 30 round rifle mags, I don't keep those fully loaded either. Am I overthinking this, or is it good to take ammo out every so often? Is there some way to exercise the springs? The other issue I can see having is that I have no idea how much ammo i have in each gun. If I had each mag/ clip filled to capacity, I would know exactly what is in each gun.
