Weapon making: Q3: How do you hide hands?

[SWAT One]

Alright, so I am making a weapon and I am wondering if I need Collision boxes on the projectiles and weapon itself, such as when you pick up a weapon or when a projectile hits you.  I need this done soon so I can get it to my scripter.  Thanks for reading...
Problem Solved...

Alright Question #2:
I tried exporting it and using the default gun's script with a few edits.  I used the weaponname.dts and bullet.dts but the model of the weapon fails to show up ingame.  The bullet however, does.  I have mountPoint and muzzlePoint joints on the gun, but it still fails to show up ingame.

Am I missing any joints?

Final problem/question:

How do I hide both hands?

raycasting.

collision is players colliding with a brick, not letting them go through it.

though I dont know if it's different with modeling/scripting.

Items don't need collision boxes and projectiles can't have one.
