Wilson Combat's 7-round follower should fit. Their kit with follower and spring is their #19. It's at Midway as #509-361.
You may also be able to bend the followers you have to work better. If I remember right, those magazines you bought have Colt/Metalform bodies. Not sure where the followers and springs came from.
