Another Hornady critical defense user here also. The only thing in your entire post that was questionable in my mind was the military switching to hollowpoint ammo. I understand some is used, but as far as I know it is still against treaty.
Everything else sounds spot on to me, including the FBI switching back to 9mm for the reasons given. Go back to that gun shop, she knows what she is talking about.
Now I don't have any personal information, but I don't think hollow point ammo is forbidden by treaty anymore. If I remember right dum dum bullets were forbidden and many people took that to mean hollow points, and that may be correct, although some took it to mean a fragmenting bullet instead of an expanding bullet. At any rate I think that treaty has been changed. When I started on the police department nearly 52 years ago, we were forbidden to carry hollow point ammo, but it was probably 35-40 years ago that the standard issue ammo became hollow points, after the Dallas Medical Examiner's office did a study, using military grade gell, that concluded the hollow points were safer; less penetration, but as much knock down power, less likely to go through and hit an unintended target, etc.
