I would love to get a gun....but I am nervous about it. I have 5 kids in the house.....I have a Louiville next to my side of the bed./
I have taught many hundreds of people firearms safety and how to shoot.
I recommend that you take a firearms safety course. It will familiarize you with firearms and reduce your nervousness. If your state offers concealed carry permits (most do) and training is required (many require it), a CCW course is an excellent way to find out about firearms, firearms safety, and the law regarding deadly force.
Take the course. Your eyes will be opened. Even if you decide that a firearm is not for you, the knowledge will be more than worth the effort.
There are many techniques that allow the mix of kids and firearms safely. Kids have more fatal accidents with bikes than they do with guns, and for more with swimming pools than with guns.
