The Glock 10mm is known as a bear defense round and it needs to be bumped up to class 7. In real life lots of people keep a Glock 10mm by their side as a close range defense weapon. It is used to kill varmints, defend against wolves, and defend bears and other agressive animals. That's all I need to say.
If anyone knows other weapons that need a class recommendation change, please say in the comments.
