How do you equip a weapon without shooting?

[khortez]

I've tried this quite a bit by myself but it seems like i only got it partially working. How do i make it so when a person equips a weapon, a projectile isn't shot automaticly? so far I've got it to where you can equip it once without shooting. But if you unequip a weapon then requip it again, it'll shoot. Any ideas?
