Best Way to Handle Animated FPS Arms?

Hey guys.

I am just looking for a little discussion here. What is the way you guys handle animating arms and weapons in an FPS style? I was thinking I could just import my guns into the Blender file for the arms and animate everything there.

I am not sure if this is the best way to do it though. My programmer self finds art hard

What do you guys think is the best way to handle this sort of thing?

Thanks,
Kyle
