I currently do not carry a firearm.. let me just get that out of the way. But for home defense I am thinking about buying a pistol. I have decided on this over a rifle/shotgun/ because of my theory (fear, perhaps) of it being grabbed during an invasion. As for caliber, I am a little undecided. 9mm, 45acp, etc.. Even though I'm all for defending my family and property, I do value life, and would rather stop the perp instead of blowing him up. I would definitely fit it with a surefire light for identification. I have thought about the Glock 17..just something standard. I have shot 9mm and found it rather fun, but nothing else. Also, the clerk at my local gun shop advised a Smith&Wesson revolver, but I would prefer something more enjoyable to practice with. Thanks!
