Plz Help

Hey, im working on a mod for a game, and i have made 2 differetn weapon models, the rifle, and the minigun. i put them in game, and i can switch, but the other players can't unless i send them my default.bind.cs does anyone know how to make this server side? like so when you get into the game, u push F7, and you change to rifle, push it again, and u change to minigun. Any ideas?
