Once again to you, I have loaded guns, I have kids, I have kids come by ... I now have grand kids.
I will never use one of your devices. My firearms are for the protection of my kids, my wifes and my life and our property. That is their principal use ... I do not want them to be safe ... Iw ant them to be understood, by my family, by their friends, and BY GOD BY THE PERPS WHO WOULD TAKE OUR LIVES. We also do some hunting.
My kids have been properly educated and trained all of their lives. Their friends have been informed and know the score at our home as do their paretns.
The same was true for my parents before me, and theirs before them. It is true for literally hundreds of people I know.
THAT, IMHO, is the answer. Education and training. I do not want to spend the extra time ejecting, take the chance of forgetting its in there or wonder about my weapon in that split second and critical time that I need to use it or die, or see one of my own die.
I pray that never happens. I have prepared myself and family on the chance it may. If a terrible accident ever occurred with one of my firearms, I would get solace from my God, just like if one of us were struck by lightning or hurt or injured in a wreck. Then I would move on and continue to educate and train.
Hope you "get it". Education and traiing are the key ... not something that renders the weapon impotent ... or "safe". It is not meant to be "safe", I do not ant anyone in my house, either bidden or unbidden to ever get the impression that they are "safe". It is an oxymoron.
You of course are free to pursue your avenue and your course. But I would never recommend any device that had the capability of rendering a firearm completely useless.
