Can i ave a little help with some commands that will help me with the LG and RG online?

I was just wondering what i have to do, if there is nething that will stop the RG lag between pressing fire and the gun actually firing, and the "wet noodle" effect of the LG? Im a CS player but love Q3 :) so plzzzz help me

Thx in advance
