Dave, I totally respect your personal experience. Nevertheless, investigation into the physics of spring steel will show you that a properly-made magazine spring will not fatigue under constant compression if it's within its designed measurements.
If your Beretta springs were failing, they were badly made springs and would have failed anyway - in fact, probably sooner had they been constantly loaded and unloaded. Such springs should be replaced whether or not you unload them for long-term storage. I'm aware of a failure (fracturing) issue with 92 slides some years back. That didn't prove that open-slide semi-auto designs are prone to fracturing; it just proved Beretta made some bad slides. And that our military needs a new sidearm . . .
I've heard just as many old-timer's tales of 1911s left loaded for 50 years, that subsequently functioned perfectly. But even those are just anecdotes; it's the physics that tell the truth.
You're totally right, and our old Beretta's were worn out before the first shot was fired. I'm sure the sand and moon dust didnt help anything. But now it has me paranoid that MY magazine springs will suffer this fate so I store them carefully in pristine condition, in my safe
