Hi my name is Dean I'm new here and I live in Florida. The reason I made this account is, I'm 16 and I have been shooting multiple times with my friends at Ranches. My friends have been talking to me and I've expressed interest in owning a firearm, one I have been looking is the Benelli Nova. I've owned a high power pellet gun for about a year and a half now and a bb gun before that, I would consider myself responsible with a firearm. My dilema is my parents aren't anti-gun but they don't own any either so I was wondering what you guys were thinking, and if it is a good idea how should I approach my parents?
