I started my daughter at 5 years old under TIGHT supervision. It was something we did together for all the time she was growing up. For her 21st birthday I gave her a cased nickel Colt Python. The solid oak case (made by me!) has a brass plate engraved;
"Ride hard, Shoot straight, Speak the Truth
and Dread Nought but the Wrath of God."
She's 37 now, with a daughter of her own, and is the director for four group homes for severely physically and mentally handicapped adults.
It depends upon the kid, the parents, (not me, but my wife, obviously!), the grand parents, the environment, the discipline and the goals,...and, of course, the love.
And obviously, if one feels it's not yet right for their kid, that's a good call. It probably isn't right yet.
(Goodness, is that a rant?
I do apologize.)
Best regards to all,
Gunny John
