If you don't like the inspect animation, you can turn it off for most skins. Instructions: install the desired weapon, open the #Remove Inspect Animation folder, select the appropriate skin and unpack the models folder into the game folder (on v34 it's cstrike, on the latest versions it's custom/WEAPON_NAME).
