Something I just learned about. The AR style 410 shoguns. A 410 slug is a man stopper. 410 buckshot is also a nasty round too. Even birdshot at close range (within a house ) is something most folks would pass on. The recoil is very manageable and it would be adequate for both home defense, small to medium game animals. You could even use it to hunt birds. 5 round mag fed (bigger mags available) semi-auto. Fast reloads, light weight ammo (in comparison to 12 ga.). This is now my new choice for a home defense weapon, along side my pistol.
