Empirically, gun accidents are very rare. They are scary, but it's often the less-scary stuff that gets you.

Obviously you should be careful, and of you're not, I'm sure the odds are a lot worse. But empirically, it seems most people handle guns somewhat safely. Perhaps because they are scary.

That being said, if you don't feel comfortable being safe with a gun, don't get one. Or maybe you just don't want one more thing to worry about.
