My wife and I had never shot a handgun before. We often commented when watching action movies -- "is it really that hard to hit something??" We decided to go see for ourselves.
They gave us nearly an hour of free instruction on the different kinds of handguns, and then the safety and firing of one. We then went into the range and split a box of ammo on a Glock 19.
At the end of the session, we were convinced we could kill anyone -- as long as they were no more than 20 feet away and stood stock still while we took a minute to empty 5 rounds into them...! :)
