Mas - I've read several articles by you and other writers talking about the merits of shotguns and/or AR-15s for a home defense weapon that might be shared by family members. I currently have a 12 gauge Winchester Super X2 semi auto with a 24" barrel and extended magazine tube with fiber optic sights. It shoots fairly well with slugs and I have a good supply of 00 buckshot. I have two concerns: one is how my wife and daughter would handle the recoil and the other is over penetration as a threat to others within my house and outside as well. Would an AR be a good compromise - especially loaded with some 40 grain frangible rounds? I suspect my wife and daughter could manage the recoil much better and with a 30-round magazine, a defender can put out a lot of rounds in a hurry should the need arise with an intruder. Thanks for your insights as always.
