Thank you for being man enough to share. I have had it happen to me on 2 occasions. I shot out my dining room window will checking the trigger pulls on 2 different j-frames. My fault.
I shot a hole in my truck door, faulty firing pin. It was dirty and stuck in the fired position. I do not try to minimize my own role in either event. If you notice, you have to be breaking more than one safety rule to get hurt, usually.
People say crazy things, about this type of occurrence, and they often mean well. There is always the Mr. Perfect who will endlessly pontificate about how stupid you are, and how smart he is. He can **** up a rope. At one time in my life, it would mildly annoy me to check a firearm, hand it to someone, and then see them check it again. Not anymore. I don't care how many times one is checked, or re-checked, or re-checked again. Pride goeth before a fall, right?
I shared my story, when it happened, not going to re-hash it here. My hope was that it would make at least one person be a little more careful. I am sure that you want the same to happen from your experience. Thank God that nobody is hurt. It happens. It can happen again. Always plan for it to happen, and maybe the chances of anyone being hurt can be minimized.
