Toy guns are controlled by law, because they are not real they are not protected by Constitutions. Empty holsters are for Places off limits to firearms so that is pointless.
As far as his embracing the reality of the Adult responsibility, or Stress of a situation, well He has been around firearms since he was born, he was under strict rules until age 5 not to touch, or even look at my firearms whether they be displayed, or on my person. The only time he was allowed to look at them was during Cleaning as I would teach him the different parts to learn their name, & function.
Since age 5 he's been firing My 1911, 357, 38 pistols & rifles varying from a 10/22, 30-30, & 410/12 gauge shotgun. He is an only child, and has been home schooled so while he may not be as Mature as one of us, he is more than most kids his age, & has not had the outside influences by the punk/gangsta mentality of today's kids.
While Our modern gun culture is not that of the 1800's he is well aware that kids younger than him from that era handle firearms on a daily basis, and that these are tools for hunting, defending, and he knows the irreversible consequences of what firearms can do to animals as well as Humans.
All this being said, this is why I brought this up, I wanted to see the thought process, Ideas, and concerns from the same group that went thru the last controversial situation. Only here this senario has yet to take place, and instead of a gun being the subject of topic, it is a topic of the subject.
