great guns but no disrespect here but its one of the worst choices for home defense. If you want the best home defense weapon then nothing is better than a 12 gauge pump shot gun with a short but legal barrel. The reason is simple. A shotgun is simple to use and does not require a great deal of motor memory skills. second is that if you are in a situation in which you have to use it in your home, you dont have to be exactly on target with it. a rifle and hand gun you will have too. keep in mind that there will be a great deal of distress being experienced at this time so aiming isnt the best for anyone. another very big and i mean big deal is that with a shotgun you dont really have to worry about it going out side the room or at least though your house to the outside. with that rifle or any for that matter. it will go through your house, your neighbors house and your neighbors neighbors house. I think we can all see how dangerous that scenario is... just my opinion....
I must respectfully disagree. I respect the choice of a shotgun for home defence; however, such a choice should be made with facts considered, instead of long standing myths.
All firearms used in a defensive situations should be aimed at the target somehow, whether it is looking through sights, looking down the top of the barrel, or looking down the slide of an autopistol. The firearm must be pointed at the target to hit the target. Hollywood has given us many bs lines about only having to be close with a shotgun, but the truth is, that at inside the house ranges (10-15yds.), with an 18" or longer barrel, the cone of shot is not wide enough to eliminate the need to aim.
Virtually all firearms/ammunition combinations suitable for self defence are capable of penetrating the interior walls of most homes and still be lethal to those on the other side. The 5.56mm cartridge, in most loadings, tends to penetrate less than typical handgun and shotgun rounds do after going through a typical interior wall. This is one of the many reasons patrol carbines in 5.56 are gradually replacing shotguns as law enforcement's long arm of choice.
I'll agree with you that pump shotguns have a simpler manual of arms than an AR-15. Those who rely on a firearm for self defence should practice/train enough with it to become proficient in its use. The AR-15 is not difficult to become proficient with.
