I have seen people in some videos changing weapons from right hand to left hand. I know that this is a console command, but I dont know what the command is. Can anyone tell me?
cl_righthand 1 - Right hand cl_righthand 0 - Left hand
in console bind "keyname" "cl_righthand 1" <hit enter> then bind "keyname" "cl_righthand 0" <hit enter>
Change keyname to whichever key you want to perform that action.
Alternatively you can use
bind KEY "toggle cl_righthand 0 1"
to have the switch on the same button.
