I followed the physics gun blueprint from the content examples, i have also made some tweaks to it which makes the object follow the player camera X Axis rotation, the problem i have with this is that once i drop the object it will reset it rotation back to what it was before i picked it up.
Can you send a screenshot of your blueprint please :o ? It will be easier to see what is wrong 
Hi LukePGM,
I posted a solution to your first issue that may fix what you are seeing here. It does however cause the object to always rotate to the player when first picked up. I am looking into a solution for that now.
