Can you modify CS:GO gun stats server side? Or is it always required for the client to change their own items_game? And if so, how do you host a server which only people with the same items_game can join?

Also: can you create custom guns (with custom models) without having the client download anything? And even make them appear on the buy menu? No, right? CSGO's buy menu is only editable clientside, is it not?
