Team Fortress 2 Model Help

[Bertruam]

I have recently started modeling some weapons for the steam workshop, but the weapons I make always end up floating over their heads. How do I correct this problem?

That floating usually occurs when the model doesn't know which bone to attach itself to. Are your models skinned to the appropriate weapon bones? Also, it would be helpful if you could post your .qc file to take a look at.
