And why are they not useful for self defense? Hits hard, low recoil, lots of rounds.
So, how is having a weapon like that helping in the situation of an armed intruder?
Homeowner: I have a semi-automatic weapon!
Armed Intruder: Prove it!
Homeowner: Well, I'd have to shot several shots in quick succession which could be risky to both the stuff in my home and those living around me.
Armed Intruder: I hear that. This is why I use a simpler gun.
Homeowner: How is that working for you?
Armed Intruder: Pretty good. I mean, people fear any type of gun, as long as they don't look like toys. And guns that can spray bullets really only draws attention. I want to be in and out before people know what happened.
Homeowner: Interesting. Maybe I should consider switching the type of gun I have.
Armed Intruder: I can't say that you have a semi-automatic isn't a big deal, but to be fair, if you were armed with a shotgun, I'm more than likely going to flee immediately. Not looking for a fair fight.
Homeowner: I never really considered that before.
Armed Intruder: Most NRA types don't.
Homeowner: I've got several other guns I could grab if you'd let me.
Armed Intruder: No problem... I've already grabbed what I wanted. Have a nice day.
Homeowner: You too... hey wait a sec...
