Ive been trying find mus_widow_jingle,mus_widow_sting,and the bump sound for walking against a perk machine.I cant seem to find them.If you where they are can you tell me?

The issue ive been having has been trying to figure out how to change where the gun model is in third person.Here are some pictures showing what im talking about.

I have no idea what im missing that causes this issue.I have a video showing the issue.
