Do custom rigs and tools not work together?

ill keep it short. i have this rig and i want to use a tool with it etc etc etc but the tool wont equip properly when you hold it out. Is there a way to fix this?

Maybe you can find a plugin that helps you align the tool grip

u need attachment for this situation (im not 100% sure). It should called RightGripAttachment and be inside the right arm. Then position as u like
