How would I go on adding a grenade lancher?

How would I go one for adding a grenade launcher for SMG for TTT? Because I want it to be a T weapon with grenade launcher :confused:

-BUMP- Help? I really need one and I don’t like going on the hiring thread and buying a code since the scamming idiots…

If I remember correctly, the HL2 SMG is already equipped with a grenade launcher. Just no ammo is given for it. Try giving the player “SMG1_Grenade” should work properly.
