I thought about this today, based on things I've been hearing on Facebook and the current proposals to ban magazines that hold X number of rounds.
It was Joe Huffman's excellent post and video
I hope he doesn't mind me embedding his video
40 shots. Under 17 seconds. 10 round mags So what if Joe uses my Sig P6 with 8 round mags instead of his STI? Great, so he has to reload one more time, adding maybe 2 seconds. 40 shots in 19 seconds.
By comparison in these mass shootings the murderer has an eternity to methodically kill innocent people. He is the aggressor, he has the advantage of defenseless, unarmed victims and no one shooting back. A matter of a few extra seconds to change mags doesn't change things for him. Contrast this with someone who has to use their gun in self-defense. They don't have plenty of time. Things aren't likely to be happening slowly and methodically. Hell, there may be more than one assailant. No. Someone is trying to kill them, and they need to stop the threat NOW. Having their gun run dry could quite literally result in their death and / or the death of their loved ones. Having their gun jam because of crappy 10 round "reduced capacity" mags could be the difference between life and death.
When a crazy psycopath is murdering a roomful of sitting ducks an extra mag change or two is of little consequence. When a person is defending his or her life or the lives of loved ones it means everything. This is why you don't see cops on the street clamoring for their departments to ditch normal magazines and issue them 10 round mags.
I would love to have anti-gun legislators watch this video and then tell me that unarmed people are supposed to effectively rush and kill / subdue a murderer after he stops to reload his gun with 10 round mags....
