I am building an FPS game and I have arms with pistol and some animations(reload, fire, idle, walk).(in blender)

Currently I am stuck, I don’t know what is the best way to use these animations in Unity.

I see 2 possible ways.

1. Import both hands and a gun together from blender and have 1 animation controller on the arms
2. Import arms and a pistol separately but then I would need to have two animation controllers, one for arms and second for a gun to apply the animation.
   

First approach is not flexible as gun is not a prefab and I can’t really swap weapons.
Second approach requires me to manually adjust the gun in the hands so it kind off breaks animation from blender where everything was positioned as needed.Also I need one more animation controller for the gun as it woun’t be animated without it.
Help please 🙂
