Weapon model

Hey all,

I’m working on making a prop model into an actual weapon model meaning it’d held and attached to hands, how can I do this?

Helpful feedback would be ultra appreciated.

Thanks in advanced,

I’m no swep creator or anything but I feel like the SWEP Construction Kit would be very helpful for you.
