I am unable to reproduce this, using the master branch as of this commit

Steps i tried to reproduce the issue:

1. devmap mp/ffa1
2. /give all
3. switched to first person
4. switched to concussion rifle
5. fired a shot, and observed weapon animation
6. don't move
7. fire a shot again, observed weapon animation again

Believe this is fixed now, and this issue was specific to tribes only.
