all 3 learned to clean a firearm before they got to shoot actually. Was part of my plan to prevent firearm issues. I never locked mine up. they knew where they all were. when they were little, I let them handle them. then I made them dissassemble them and clean them because they were handled. nothing like a 6 year old frustrated beyond all get out because the mechanical issuses are at the limit of their understanding. Basically I taught them to associate handling them with it being such a big PITA to clean, that they became tools, not "ooh shiny" hidden in the closet. Seems to have worked perfectly. AFAIK they were never messed with. But I digress. All 3 learned to shoot, all 3 have helped me reload, and all 3 (well 2, the one's a bit young for that yet) received a pistol as a wedding gift.
One of them actually still shoots with me from time to time. She enjoys competing with me for bullseyes. I get to play equal parts proud dad and "stay away from my daughter psycho dad" at the range when she turns heads with her targets..
One covets my 1911, the other loves her revolver, and the third seems to be developing a soft spot for the hi-power. couldn't be more satisfied.
