I had six 30-round Thermold magazines fully loaded for over two years before running them through my CAR-15. They all functioned perfectly.

What kills a magazine, assuming that they're quality magazines, is the repeated loading and unloading of the magazine which eventually fatigues the metal in the spring.

I usually have a number of magazines for my guns. If one fails to function properly because of worn springs, I replace the springs. If the feed lips get bent, I usually replace the magazine (thats why I like the Thermold magazines for my AR - they don't bend).

Yeah, my XD came with one of those... I think it stinks though and I don't use it... it's a DIFFERENT difficulty than just loading normally but it's still just as difficult if not more so... loading by hand, IMO, isn't that hard once you do it a few times...

I have a Uplula for my pistol magazines. Greatest mag loading tool I've ever used. Better than the one that comes with the Glocks and the HKS tool I've used for my Hi-Power and Cougar.
