Not exactly a stellar performance, but kiddo had a little trouble with the heft of the ruger markII without a rest. It's also very large for his hands, but he did control it well at first, only having trouble with a proper sight picture (shooting low). The smile on his face when he connected was still a proud papa moment. Seeing the can spin around made him laugh - they were full, and I exploded the other 4 showing him how it's done after he was fatigued and the barrel was going all over as he was trying to aim. So yeah, he's hooked!
Last summer he had trouble pulling the trigger more than 6 times and was shooting off the fence rail, so we're making progress. He was all into loading the magazine, even though he couldn't hold the follower back with one hand (so I held it for him as he loaded it).
It was the best birthday present I got.
