The shooter is DQ'ed not the gun because it didn't do anything wrong. If you spend the money to travel to a big match and DQ then hopefully that will reinforce the lesson and you'll learn from it before somebody gets hurt, if you don't then your hobby just got a little more expensive for you. I know shooters that have been doing this for a number of years and have never DQ'ed but I also know a couple that have DQ'ed several times, why they keep doing the same thing over and over I'll never know but it happens. Let's not try to read too deep or interpret things that aren't there, it's been like this since the early days for a reason. I'm not saying we should never change anything but this is a safety issue and it's there to keep us from getting hurt.
