870 tactical with tube extender and lower recoil loads is a great home defense firearm.
Hard to argue against if you ask me.
Loaded with 8 shot so I do not shoot through any walls. An AR type weapon in the house begs for collateral damage. Shotgun or handgun.
Concerning self defense? It's hard to beat that ominous "KA CHINK" sound when you pump a round into the cylinder.
In truth, however, my cocked, locked and ready to rock Glock 19 with tac light is my bedside gun.
