Hello, I have been looking at handguns, mainly Glocks and want to get one for shooting at a range, safety and just to have a gun. I have never owned or used a gun before. I really want a Glock but their are so many models I don't know where to start. Please recommend me a Glock model that would be good for this. By the way I have no idea what caliber I want or really any idea of about calibers.
