Before last week, I had never fired a handgun. However, I did attend military school in seventh grade, where I had to handle an M1 Garand, the semi-automatic rifle that Gen. George Patton called “the greatest battle implement ever devised.” I say “had to,” because I really didn’t want to after they warned of “M1 thumb.” To insert the ammo, your thumb enters the chamber. If you don’t pull the bolt back far enough, it can release and smash into your thumb. Anyway, I joined some newsroom colleagues at Sharp Shooting Indoor Range and Gun Shop last Wednesday to learn more about guns and blaze away. I practiced with a 9 mm Glock, which is safe to load, but I was still wary. Dave McCann, a local businessman and firearms aficionado, was my trainer. He detected my flinching and instructed me to concentrate on the squeeze of the trigger and the target, not the coming sound.
