All my mags stay loaded to the max, but Simply loading them and leaving them loaded for Months won't completely break in the springs. You do need to exercise them, but it doesn't absolutely mean by shooting... It's just more fun that way.

I broke mine in using an eraser head pencil... repeatedly pushing the follower all the way down with the eraser end of the pencil, like churning butter, while watching TV.
While that made loading rounds 1 though 6 easier, after more than 2.5Yrs of shooting my Shield Bi-Weekly, it's STILL tough to load that 7th round by hand.
