One of my 226 mags is all beat to hell up at the top around the lips/follower. Maybe from being dropped or ? I noticed that the follower does not come up as high as a good mag, so the slide does not lock back only when using this mag. What does the follower "trigger" to lock the slide back? Can a worn follower "rock" inside the mag and allow this also?

When the magazine is empty, the follower makes contact with a tab on the slide catch lever and lifts it up to catch the slide while in full recoil.

Is that the notch in the front left corner of the follower?

Yes.
