So I just picked up the echelon 4.0c and I love it, it runs beautifully and it's one hell of a gun. My only issue is that the mags are a bit loose and seem to rattle. Has anyone else had this go on with their's, and if so, is their a way to fix it, or is it a non issue that just takes getting used to? and does it happen with ant other guns?

(All rounds seated in mag and it's not ammo rattle in it, it's the mag thunking around in the grip ever so slightly)
