My dad used to be a gunsmith before transitioning into being a Machinist/Tool & Die maker. Sometime around my 3rd birthday, (1977) I received a plastic 1911 replica with safety, removable loadable magazine, working slide, and little plastic cartridges that would fire a plastic bullet a short distance, and then eject the "brass" when you worked the slide. I loved that toy.
But they say the cobbler's children have no shoes, and so it was that I never fired a gun until I was almost 19. 5 rounds out of a 4" S&W Model 28 kicked so hard, I thought twice about trying my Series 70 1911. After all, I reasoned, 45 hundreths of an inch must kick harder than 38 hundreths, right? When I fired the .45, and that slabsided heavy frame soaked up all that recoil, I fell in love.
Didn't shoot again until I was at Edsen Range a few years later learing to fire the M16A2. Then aboard MCAS Yuma, I was trained to use the Marine Wingmasters in '99. Later that year, I experienced my first dove season.
After my kids were born, my borderline anti-gun wife decided that mommas need to know how to shoot so we got her a gun, and I taught her to shoot.
When my son turned 5, we practiced the four rules and some target shooting with a pellet gun. Now as soon as I find him a pistol he can fire, or a rifle with a short enough LOP, he will learn to shoot .22LR.
