Not always true. Some mags, like the 8 round Checkmate with "Bullnose" follower compress the springs so much that they will wear out fairly quickly if left loaded. I have a number of these mags and all the ones I left loaded starting having feeding issues after a year or so. Pulling the springs out and comparing with springs from new mags confirmed that they were quit a bit shorter and weaker.

Some mags don't compress the springs as much, especially GI style 7 round mags. This is probably why you'll see stories of military mags that have been loaded for decades that are still good.
