Tell you what, Mike. You have some guy a lot bigger than you grab you by the hair and drag you, punching you in the face, while you jack that fake round out of the chamber. Or, you arrange with a friend to do a pretend - and very surprise - home invasion (load your gun-jammer bullet and a bunch of empties), and see if your tunnel vision, tunnel hearing, shaking, adrenalin dump, and loss of fine motor coordination let you manage to remember to jack that one out, or if you automatically raise, aim, verify target, and fire.
I've been in that first situation, by the way, and if I had had to jack a round out of the gun, he would have taken it away from me. It's a clever idea, but has no real life application. I keep and carry my firearms for self-defense, not game and giggles.
I think, by the way, that getting insulting to other people on here is pretty obnoxious and self-serving. If you can't take criticism, you should probably get out of the inventing business.
