Springs wear out by being cycled through their range of motion, not by being loaded or discharged for long periods of time. Actually firing off the rounds and reloading the magazines causes fatigue cycles more than keeping the thing packed for even months or years at a time.
E; I'd like to amend this slightly, spring steel is a very cool and based material, the conditions where it would fail catastrophically or in function would be US issue STANAGs that have been in use since fucking Grenada as training magazines, your general purpose magpul springs fresh off the factory have a fatigue life measured in years if not decades.
I've always been a believer in Magpul, I think I have at least one 30 round filled for over a decade. I think it's been scientifically proven at this point leaving a magazine fully loaded makes no more wear than loading it and immediately firing it. I think the whole "leaving magazines loaded harms the springs" concept was just something marketing cooked up to sell "duty grade" "+%15" magazine springs, IIRC Wolf was a huge seller of "duty springs". The firearms manufactures literally spent trillions of rounds of ammo finding a spring that will not only stay strong enough to load that last carttridge but also not create excessive binding on the slide when it is reciprocating when loaded to maximum capacity. Like many other things in the firearm engineering community, this problem was solved before the first production guns left the factory but in usual FUDD fashion someone pretended like there weren't dozens of engineers solving the problem before it ever was a problem.
