Same here if you ever get a link give it to me 
If we gave you the link you would spam crappy add-ons that don't work.
I will show you an example code of the gun script. When you start scripting, its best just to "Borrow" scripts (with permission, exept from the default weapons of course) and looking at scripts will also help you learn how coding works.
Lets say I was going to make a "sniper rifle" type weapon. Heres an example single-shot gun: (zoom in to see)

It looks very long. But not as long as it looks.
Also, don't use sketchup alone. Possibly use it as a rough model and then import it into another modeling program.
