I've been searching but couldn't find anything. I was wondering who can ask to see your form 4? Say for instance if I go to a range can the staff ask to see my form 4? Or would a simple acknowledgment of saying "yes I have a form 4" suffice? I'm sure since it's their range they can do as they please but legally can they request my form 4 and hold it temporarily while I shoot? I'm just worried of showing my form 4 and they take my information down for whatever reason...
