That is goofy. Did she not have to change mags at all during any of the stages she completed?
I'm not a huge fan of the long take up on the Glock, but fully understand why it's there. I've kitchen table gunsmithed my Glock's, but the one thing I stay away from is messing with the take up. That safety thing is pretty important IMO.
Hope she recovers and sticks with it; albeit with a functional gun.
