I havent had this problem, I have 6 WC mags all off them work great.
One thing I will mention, is if you over tighten the grip screws it might grab the side of the magazine creating a tight situation. The boss the screw feeds into on the Smith frame came loose on mine one time. It had been striped at the factory, I orderd new ones (free) from Smith.
I just bought new WC grip screws the other day and they went in with out a hitch.
I currently use Houge rubber wraparound's
