There is no need to call the guy paranoid.
There are times when a back up makes good sense, I carried one to work daily for 27 years. Yet taking four handguns on a trip to meet the potential in-laws is a little over the top. If I had a potential S.I.L. show up with one gun ok, two guns maybe, but more than two and I gotta rethink if I want him as part of my family.
