A 9 year old gets a BB gun or single shot .22, not a UZI.
My 4 kids all went from .22LR to.22mag to .303 Enfield before they were 11. My wife took a little longer to overcome her dread of guns. It took a copperhead slithering between her feet to totally change her outlook. When we go in the scrub she carries a little .410/.45Colt snake-eyes derringer thing.
When I was a Boy Scout, from age 11, at summer camp, we did single shot .22's.
Of course we also made our own slingshots.
I think David Crockett had his first rifle at eight.
I learned to shoot in the Army, for which I am forever grateful.
I had bb guns since little kid. My dad bought me single shot designed for child 410 shotgun when I was 12 for Christmas. Boy!. I remeber reading how to practice in Boy’s Life. Lie in bed with shotgun find mark on ceiling move gun and stop. Next time we went hunting I nailed a pheasant from 20 yards with my little 410. No one could believe it. Great memories.
See the vid? Trainer did a shoddy job...
The UZI was not the problem... She did fine on single shot... Full Auto was the problem, just plain stupid. Both my boys had shot my 357 magnum and my sks rifle by the time they were 9. With the 357, I was also helping them stabilize the gun, but let them feel the kick it had, I wanted them to have respect for the weapon that they really did not get from a bb gun. Neither one of them wanted the second shot without me holding the gun, until closer to about 12 years old and neither of them wanted to feel how much extra the 357 magnum shell was over the 38 shell they shot the first time either. I will say my oldest son’s first time shooting the 22 (rifle) was using a chipped toilet tank as a target, the way that thing exploded when he hit it, His eyes got about as big as fifty cent pieces... he had a healthy respect for guns before he was 6 years old and knew they were not toys. I kept them locked up because we had a lot of other kids in and out of our house, but did not worry about my kids playing with guns.
