This is a debate myself and a coworker have been having. What is the best home defense gun? Two choices here. The first is the Remington 870 12ga. with the extended mag tube. Advantages. The rack of the slide is a universal sound that will strike fear into the hearts of the most hardened criminal Will stop anything. Shot will not go through your walls and the neighbors. Does not need to be aimed precisely. Disadvantages. Slow to reload. Clumsy to turn with, and if in a hall the gun will not be pointing where you are looking if you do have to turn. Requires two hands Next up is the Glock 19 9mm. Advantages. Idiot proof. Holds enough rounds to stop anyone. Fast reload. Disadvantages. Need to aim. Bullet will carry a bit. Not terribly accurate. No safety. Now experience has taught me the 870 works just fine when it comes to stopping a burglar, or in my case 4 that were breaking into a trailer. Plus I am comfortable with shotguns. My coworker swears by the 9mm. Dear readers, any thoughts?
