“Hey, Mitch – why does anyone need a magazine with more than six or seven shots? Future president Joe Biden assures us two is all you need!”
I’m going to answer you with a question. Several, actually.
First: are you ever going to be attacked by someone who wants to kill you, then and there? If you answer “I have no idea“, that’s a perfectly valid, honest answer. Violent attacks – robberies, kidnappings, rapes, aggravated assaults, spree killings, terror attacks – are exceptionally rare. Rarer still if you have no criminal record, don’t associate with criminals, and don’t work in a business where a lot of criminals are part of the clientele. That accounts for the vast majority of people.
Not a single person who gets robbed, kidnapped, raped, suffers a home invasion, or is at a location where a spree killer decides to stage their blaze of glory, woke up that morning thinking “I bet I’m going to be the target of a violent incident today!“ Did they?
Second: if the person decides to attack you with the lethal force we mentioned above, and you decide to defend yourself, how hard is it going to be the end the threat to your life?: impossible to predict, right? Many robberies, assaults and rapes, and even a few spree killings , have been ended by a good guy pulling out a gun, with no shots fired. Sometimes an attacker falls over unconscious, or dead, after a punch to the face. On the other hand there are records of people who’ve been shot 20 times and still had the strength to shoot, stab or hit before they bled out. I know one story of a woman who barricaded herself and her kids in an attic during a home invasion; when the guy broke into the attic, she shot at him six times at a range of 2 feet, hitting them five times in the face and head – and he lived without a lot of complications ( other than a lengthy prison sentence). Alcohol, drugs and mental illness all affect this as well – drunk people are harder to deter from doing stupid things; people who are extremely high may not experience pain, even pain from a gunshot wound. There are cases of people who were very, very high who never noticed they’d been shot until they bled to death.
So the question is: how many shots (if it’s a gun you choose) will it take to stop one person from following through on trying to murder you? The answer, given the evidence we have seen above, is “0 to 20 shots – maybe”.
Bear in mind that, under stress, almost nobody hits their target with every shot. Even at close range. Even if you practice shooting a lot (although that helps) the police, in self-defense situations, hit with an average of about one shot in every six. Put another way, the police fire an average of 17 shots to end an engagement.
So – you don’t know how many hits you’re going to need to end a lethal or threat to you (or your family, or innocent bystanders), and you don’t know how many shots that you fire are going to hit the person who is trying to kill you.
That’s with one attacker.
Which brings us to the third question
Third: how many people will be trying to kill, Rob, attack, rape or kidnap you?: The scenarios above are predicated on one attacker. Can you predict how many people are going to attack you?
In my city, a few years back, there was a series of home invasions. Four people would break into a house, violently subdue any occupants who were present, and take what they wanted.
Nobody died in that series of incidents – but other home invasions do lead to murder, almost always murder of unarmed people.
Remember – none of the victims woke up that morning thinking “I bet I’m going to have a violent home invasion today”.
Now – if you hear somebody kick in your door in at midnight, ask yourself – how many of them are there? Are they armed? Are they drunk or on some sort of mind altering substance that warps their perception of risk, danger, and/or pain? How will they react to someone resisting (or not resisting)?
You are not going to know. All you know is that there is a potentially lethal threat to your life down there. Maybe the sound of a pistol racking up will send all of them scampering from your house. Or maybe the sight of one of them falling over, gushing blood after you shoot one of them will send them running.
Or maybe you pull out your six shooter, and fire all six shots of the first attacker you see – leaving you holding an empty revolver while robbers two, three, and four come at you with baseball bats, ice picks and a shotgun.
So the answer to your question is “When we are responsible for defending ourselves, our families and our community from a violent threat to our lives and we can’t predict who is going to carry out that attack, how many of them there will be, and what it will take to deter/stop them, we want a magazine that is less likely to run out of ammunition before the attacker runs out of attack”.
I hope that answers your question.
