my advice would be to go and download a GUI. the cevo gui is very easy to upload in your cfg and use. http://www.cevo.com of search cevo gui you will find it….. with taht u can bind anything very very easily for quick switching etc.. for example i press N it buys a nade.. i press c it quick switches my HE nade…. F quick swqitches a flash.. etc etc… i do use q for pistol/rifle..
