I think there are shooters that haven’t had an AD, like there are are pilots who haven’t landed wheels-up. Yet.
It’s important to always think you’re capable of landing wheels up, or else you invite it. Same with an AD, IMHO. The best way to invite an accident is to assume that you’re incapable of it.
There are very few ACCIDENTAL discharges. There are many more NEGLIGENT discharges. I have had both.
Three ND's and Four AD's from the same gun. A Ruger Super Redhawk 454 Casull. At first I blamed myself And called myself some colorful names. The second time, I thought I had done it again.The third time I deliberately had my finger off the trigger.
I took that sucker home and cleaned it very well. Then I loaded it with some light lads and fired it until it did it again. Called Ruger, and they found a broken sear. No charge and three weeks turnaround. Got it back on opening day!!
An AD, as opposed to a BC?
I learned that the hard way. I did my whole military career, not one ND (negligent discharge), and I own firearms, and never had a problem. Then I cleaned and function tested a revolver a few weeks back and had to buy a new monitor lol. It was embarassing heh.
