Trying to Model Gmod ViewModel Hands?

I’m relatively new to modelling, I know my way around a few 3D modelling programs and can perform some basic stuff, but that’s pretty much it.
I’m currently screwing around in Garry’s Mod trying to make a SWEP, and I want to make it so that it goes from holding the ball from this. (

Into something like this.

On the Garry’s Mod Wiki Page, it provides a bunch of different links to different downloads for rigging etc… and I’m not really sure what one I would need for this job.

I’m pretty lost on how to model here, being a noob at modelling and all.

Any help is appreciated. :slight_smile:
