Hmmm... these debates are never easy, and can't ever really be settled with any one "right" answer.
I truly believe that for the vast majority of home invasions, having a 5-round weapon would give you at least 3 rounds more than you need. Obviously this isn't always the case, and in some situations you'd want to have as much ammo as you could bring to the table. Again, I'm talking about MOST situations!
Like most folks on this forum, I'm certainly a gun guy! I have a lot of choices at my disposal, ranging from handguns to hunting rifles, shotguns, to a few AR-15s. My bedside weapon choice is not necessarily set in stone, and it does vary a bit from month to month. I always choose a reliable weapon system that I've trained with, and can count on... but I'm not sold on the hypothetical "one right answer" approach.
More to the point of this thread, I currently keep a Remington 870 next to my bed. It is actually one of my work guns, but it seems to also fill the home defense niche fairly effectively. I've got four slugs at my disposal in this weapon, and I don't ever feel out-gunned with that firearm!
If a foreign army should ever invade my home, I suppose that shotgun would at least get me to a higher capacity weapon. I also often have my duty weapon sitting on my nightstand. But, for 99.99% of situations that I'll be likely to encounter at home, I think four rifled slugs will get the job done!
