This thread does appear to have a lot of people who don't shoot IPSC/USPSA or who if they do , do it very causally opinioning very hard on something they don't understand. You know how you feel when someone who doesn't own guns tells you you don't need a 20 shot magazine, or a dude with a hunting rifle tells you you don't need an AR, thats how I feel reading some of this.
Once again, this was a terrible tragedy, one so rare thats its caused all this discussion. We don't need to change the rules of the game! We don't need to act like the sky is falling! We don't need to put down every Labrador in the world because we heard about one biting a child.
Half cocks are to catch hammers slipping not for carry. A safety notch on a decocker gun is not the same thing.
