The purpose of the notches in the follower is to bypass the dimples in the mag tubes when you install the follower. if you didn't have the notches, you couldn't install the follower. Regardless, the dimples keep the rounds from going into the extended mag tube. You remove the dimples and the rounds will go into the extended mag tube.
