Gun not snapping to Character

I am trying to make a Third Person Shooter. I imported the FPS gun model, but decided to instead use a custom one.
When I imported the model into the FPS blueprint with the arms and gun (replacing the gun for my custom one), it works fine, the gun moves with the swaying of the arms.

This is the construction script of that blueprint

I did the exact same thing for the third person character and the character sways, but the gun stays stationary making it look very weird.

What can I do?
Any help is much appreciated! :slight_smile:

Are you attaching the gun Via a socket? or are you trying to just attach to the mesh?

I see that you are naming a socket to attach it to… But did you create a socket on your skeletal mesh with that name?
