Mag springs are no exception, my wilsons have done it too, just to a lesser extent. I guess it would've been better to say the ACT springs are too weak. As a result, they don't always feed the last round. I won't attribute the problem to my pistol, because it happens in my dad's Colt as well.
I'm not bagging on the pistol at all, I'd rather have crappy factory-supplied mags and a pistol that runs as opposed to a $50 ubermag and a pistol that still won't work.
