Mossberg .410 Shockwave for home defense. Lightwave, low recoil. If the sound of racking a round in a shotgun doesn't start the intruder running, the sound and pain of 1 - 6 shots to center mass, or ass if they start running, should do the trick.
You can range from non-lethal rubber shot or lead ball buck shot which will kill a man if hit head, neck, heart, etc. Or you could load 1 or 2 rubber shot (warning deterrent with the rest buck shot).
If you are willing to strengthen yourself for more recoil, you should consider at least a 20-gauge if your goal is to incapacitate an intruder.
No time consuming pistol permit required.
