I have some Beretta92 30-round mags (PB-marked). When they were new the spring was INSANELY strong; so strong I could barely load them even with a loading device. But now, after some light use and a few moths left loaded they are actually pretty easy to load.

I know that springs are designed to be stronger at first then "level out" at a good strength after some use, but I'm surprised at how much they've weakened.

Question:  Has anyone here used their 30's a lot? (like shooting them all the time and leaving them loaded for years on end)  If yes, can anyone attest to the long-term durability of the 30-rounder springs?

I tend to trust Beretta as the (2) 15's that came with my first 92 have been through hell and back and still work perfectly.
