I have to agree with Rick. The cases do not look like they were supported all the way. The 9mm is not straight walled like the .380ACP. the lower 3rd of the case looks like they were not supported.
If this was a test of using the incorrect ammo in a firearm, please don't do that again.
You may get lucky once.
