I’m with you...I’d be awfully hesitant to handle an Uzi myself for fear I wouldn’t have sufficient strength to control it properly!
Just load the magazine with one round. Add one or two more when you become comfortable. Firing more than three in full auto mode is not very useful anyway.
There is an awful lot of firearms FUD in this thread. People, it's just a 9mm machine gun. Sure, the little girl needed help, but it is possible for a child to control a pistol-caliber submachine gun.
With the reactions here on FR, it's no wonder we lose more rights every day.
