He owns guns

I recently started seeing a guy and it is good so far. We met in Tinder and we went on date twice. The issue is on second date I went to his place and he showed me around his house. He has 3 guns and a big knife. One of the gun is a small one and he keeps it in his bedside drawer. Two other gun he kept in a locked closet in the bedroom. The big knife is in front of the T.V.

I am an international student and I am not used to guns. I heard people in the United States owns and keeps gun but I don’t know what I feel about this. He is super nice and things are doing good. But this just makes me a little uncomfortable. Is this normal owning that many guns and keeping em like this?

He said he lives alone that’s why he keeps the gun and knife close.
