Secondary Fire: How the fuck do you use it?

[BananaFoam]

I'm in the midst of scripting my own SWEP based on the SST Morita rifle. The one I'm currently scripting has a shotgun attachment.

Though I know how to make an SWEP with proper primary fire, I never did learn how to script in secondary fire. I know you need to edit the hooks for it (Most LUA SWEPS leave it blank) but I don't know what to put. As stated above, I'm trying to make it so it fires 6 bullets at once, like a shotgun.

Also, I am using the built in GMOD base. (These weapons are super basic, well, except for the nuke launcher.)
