Reload sound effects (vanilla weapons)

[Artecus]

Requirements:

• [x] I have checked the repository for previous issues of this type
• [x] I have included a detailed description
• [x] This is one issue, not multiple issues

Just like dynamic reloads, I can't think of a reason for this feature to be left out of the vanilla game.

These already exist. So closing this. (It used to be, but steel fixed it)
