Good plinking pistol
I know padrejay asked specifically about a semi, but my $0.02 would be to start a newbie, especially for a kid, with a SA revolver. I have a Ruger Single Six .22 / .22M that I love to shoot cans with. I plan to teach my daughter, who is now 13, how to shoot with this pistol in the next year or so. Absolutely love the pics of the Ruger Mark II! I may need to purchase one soon and teach her how to shoot that one as well. Could even be the same lesson, but I just think the SA revolver is easier to "understand" to start off.
I appreciate the "cowboy" characteristics and still love to shoot it.
Padrejay, how old is your kid? I sometimes wonder if I'm waiting too long to teach number one daughter to shoot. Number two daughter is 11, and in some ways may be as ready as #1 (was blessed with athletic ability / hand-eye coordination, whereas first daughter was not). Both thankfully have common sense which may have more to do with it than anything...
I learned to shoot as a kid with an old gun from Sears that was a double barrel .22 on top and .410 on the bottom. I think I was about 10. I never really learned to shoot a pistol until I was an adult and it was with that Ruger SS.
