Thanks for all of the advice. Unfortunately I haven't been able to log onto The Firing Line since Friday, so I didn't get to see those great links and the good advice, after reading them it's really to bad, I could have used that.
Anyway, we went today and he/we had a blast. I had planned on only staying for a half hour but that was over in a flash and was just not long enough. One hour proved to be about perfect and left him planning next time.
I was very proud of him, I dare say I thought he handled himself and the pistol better than some adults I've been with (I got lazered last week by a friend of mine, but that's a different story). We did focus on fun, not accuraccy, but he did very well anyway.
One last bit of advice that I can share. It didn't occur to me until he was actually about to shoot for the first time, but he is small for his age and the target is about 6' off the ground, 25' out. I bent down to see his sight line and a shot at the target would go right into the ceiling! It wasn't obvious by looking at him so I'm glad I caught it. There was an old stool in the corner which got him up high enough and worked out nicely.
I should mention that he did try one shot through my .380 PPK. He seemed pretty excited that he did it but he wasn't real eager to do it again so we stayed with the .22LR. However, with that one shot he hit the 7 circle on a 50' slow fire pistol target (at 25'). It's on his wall right now.
That was the best time I have ever had at the range and one of those all too rare moments.
Cheers
