Change weapon model

Hi, so this is a big question. I'm trying to change the model from a weapon, especifically the "RW1" from Advance Warfare (from TheSkyeLord), and what I'm trying to do is the following:

1. Change the weapon world and view model, so the gun is the same but the model different.
The model I'm using is this one:

At this moment I'm using as both world and view model. The wm looks ok but the vm is the one mess up:



2. I want to change the reload animation, so it looks more according to the weapon, but I don't really know how to do it.

3. I want to change the idle animation so it looks more like this:



Basically move the model of the gun itself, but I don't know if it's even possible.


So my question is, does anyone can help me pointing in the right direction?
Like any tutorial you know, any tip or maybe if you have time to help me that will be cool.
Any help I'll really, really appreciatted.


Thanks :D
