Why do you need a AR 15 or AR 45 and a large mag , (say over 10 bullets) to keep a meth addict from the intent to rape you or kill your children, would not a regular pistol work just as good, they have semi auto ones now that hold magazines.
An AR15 (or ANY rifle, for that matter) is more accurate than a handgun in a stressful situation, unless the shooter has had a fair amount of training on how to HIT his or her target with a handgun.
As for the "more than 10 bullets" issue, there is no pact among thieves, that they will only invade a home as an individual. When I hear the glass break or the alarm sound, I will arise and assume that there may be SEVERAL intruders. To assume less is simply foolish.
The word "need" does not come into play in a free society. I don't know what country you live in, but in America, there is no "need" which must be proven to own several cars, or computers, or homes, or guns. No "need" must be proven before a person can do anything legal. I might want to own a copy of every vinyl record album ever produced. Must I justify a "need" for these albums before I am allowed to own them?
Also are you saying you stay awake all night to fend off people who might break into your home??
No, I sleep quite well. I have an alarm system that will awaken me, should I be required to fend off an intruder, or a group of intruders.
I noticed that you answered my question with a question. Do you have an answer? What do YOU have in your home, to deal with a meth head who breaks into your home at night? What if he enters with three other dregs of society who have jointly selected YOUR HOME for an invasion?
Please tell me what
your plan is, to deal with this real world scenario.
