Awesome!! Here's proof that you shouldn't mess with Texas..or Kids from Texas http://www.cnn.com/video/#/video/us/2009/10/01/boy.vs.alligator.KTRE Although..I don't think I'd take a 5yr old hunting alligators..or teach a 5yr old how to shoot a rifle.
He can shoot his first deer in middle school like I did 5ys old, to me is a bit young for proper firearm safety
This is Texas. Age 5 is a decent age to dual wield two hand guns, and me in mid training for nun-chucks.
