How well do the springs hold up in the Glock mags if they are loaded for extended periods of time? Im a believer that one should be prepared for anything and I like to leave my mags fully loaded in case I ever have to grab and go. My dad always told me when I was a kid to never leave mags loaded cause the springs would compress and cause ftf's. However that was a long time ago and I know that the metal used to make the springs has come a long way. There will probably be alot of different opinions on this so to each his own, but, What do "you" do? Loaded or unloaded?
