How to get gun to move with models hand?

As the title states, I have two models in my unity world currently.

1 is a humanoid model (from DAZ3D), and the other is a handgun that was imported into Unity from the asset store. Is there any way to parent and script the handgun so that it will follow the motion of the players hand?

I normally have a pretty good start with issues like these, but currently I have no starting point, and am a bit confused as to how to go about this.

Is this even possible to do in Unity? (I'd think it must be, but maybe easier in a 3rd party program...) Either way, I'd like to try a solution from inside Unity, if possible!

Thanks!
