Don't want to argue this very small point but how would the kid know this 'safety round' was in there vs an unloaded chamber. Either squeeze the trigger, and it 'clicks' or squeeze the trigger and nothing happens(chamber empty)..but it either case, if the kid knows to rack the slide-bad news..
It really doesn't 'disable the firearm', does it? The kid can still rack the slide. It's akin to a snap cap, correct? 'Disable' would mean he can't rack the slide at all.
Guess I don't get it..how this is different than a snapcap.
My understanding is that you chamber this round and that way if a kid finds your gun and pulls the trigger the round gets jammed in the gun and it won't cycle. You have to dislodge the round by sticking a rod into the muzzle and pushing on the round.
The reason most people don't like this device is that if you forget to eject the round before you go to use your gun, when you pull the trigger your gun is now disabled until you find something to stick in the muzzle to remove the round. Not a good system for a defensive gun in my opinion. If you did go this route, you better train that way too.
