Gun system - will this work?

So, right now, i have a a Ak-47 added to the default character blueprint, and Camera, i’ll also be adding a hands model to it.
In the character blueprint, when ever i click Left-Click, it plays a sound, and makes the camera shakes.
How do i make it when i can scroll wheel, and it changes the weapon attached to the Character mesh? If that makes any sense, also where it makes sure i have a weapon in my hand in order to play a sound/camera shake.

bump i guess.

You should check tutorials from my sig. As for weapon change there is a tutorial comming.
