[Glock30]

I don't really know what I am looking for. I do not know much about guns, actually. Just something for basic home protection. What would you suggest?

For a new shooter, a 9mm, probably a glock, smith&wesson, or berretta there easy to shoot and maintain then its do you want a full size (15+ rounds in a mag) or compact (10-13), if you want something with a little more kick a 12gauge pump shotgun, or in my opinion a Marlin .45-70 its a 7 round lever action rifle and if i can drop a 2000lbs bear at 110 yards, i can drop a 200lbs human being at 20ft. draw backs, it'll kill the intruder and probably go through him, your wall, and kill your neighbor and god help you if your not wearing ear protection.
