The one thing I would do different, isn't a CCW thing, but might be beneficial to the new shooter.
My 14 year old son has been wanting a .357 revolver. He's a big boy, almost man sized, but I wanted him to start with a .22 revolver before getting a .357. Just like he got the .22 rifle before his 7mm.
So for Easter him and 12 year old son both got .22 revolvers in there baskets. One of the reasons we liked the idea for the revolvers is they will shoot anything you put into them, where the P22's are ammo sensitive.
The revolvers we bought are the kind where you flip open the side rotate the cylinder and use the rod to push spent brass out. Now we have never had an AD, but son somehow skipped a round twice, once when shooting, once when emptying the spent brass. Upon reloading he found it. It scared him a little for he seen the potential for disaster. His revolver was on safe, and he never pointed the muzzle at anyone, but he seen that had he not been following safety rules something terrible could have happened, when he thought his gun was unloaded. Drill safety into the kids, and going over the rules everytime we go to the range does work.
Anyway, what I would do differently... For a new, inexperianced, or young shooter, I would suggest a revolver where the whole cylinder flips out for reloading or for emptying spent brass. Then there is no going to fast, emptying brass, so skip a live round. Sure it probably could still happen, but I think it would be less likely.
One thing I do and won't change. Take your kids shooting! But everytime you go to the range go over safety!! Make a game out of it, who ever recites the most rules, and can explain why that rules is in place, gets to shoot first. Don't just tell them the rules, make THEM tell you!!
