How to attach specific bone to actor

Hey, so I have a gun skeletal mesh with a magazine bone on it. When reloading, I would like to attach ONLY the magazine bone to a socket I have on the left hand, so it moves with the animation. Unfortunately, I do not have the mesh for the magazine, or a gun model without a magazine, so I’m pretty sure this is the only way to do it. Any help would be appreciated, thanks!

Might be possible to detach the magazine bone when reloading so it doesn’t move with the rest of the bones, but I think for simplicity and reducing code it’s easier to just load up the weapon mesh’s fbx into blender and use the separate tool to separate it into two different meshes since that’s what you really need. Will also help if you want to just place some magazines on a table or around your level… Etc. It’s pretty easy to do as you can see here and there’s plenty of tutorials on YouTube.
