Not sure how much I buy this as anyone who can describe a stock Glock trigger as a “hair trigger” doesn’t understand what that term actually means nor do they have a basic understanding of gun safety.
Before ANY sort of mechanical safety is even considered - why the FUCK did this child have access to any firearm. A safety on a firearm was never designed to stop a user who is willfully trying to use the weapon nor is it a child safety device. To imply that’s how it should be used is irresponsible and I highly recommend editing your post to reflect this.
Do you also think we should ban garbage disposals because there isn’t a safety to stop my child from sticking their hand in it? What about a safety lock for the disposal switch? Will that save the child’s arm?
