Question How i can simplify this?

I just want to make weapon changing system, so if you have 1911 you can switch to m16 at any time, what i made looks confusing, is there any way to do it better? (im new to unity)

 

You could use a layer to switch between 1911 and m16, both having the exact same states/animations.

Check the Layer tab in the Animator window: https://docs.unity3d.com/Manual/AnimationLayers.html
