About 1968 a fellow pilot at work wanted to buy a large pistol. I had a GI 1911A1 that someone had done a nice chrome job on, if you like chrome guns, I didn't. The gun looked great in a wooden presentation case.
I told him I'd sell the pistol and case to him for $75, on one condition. He would have to come out my place to shoot once or more a week until I thought he could handle the pistol OK.
The first day, after all the safety briefing, etc, I put him about ten yards from the target.
I said, That's a BG that's broken into you house and is coming at you with a knife. Empty the gun into him.
He shot seven rounds and only hit the whole backstop one time.
His reaction was there must be something wrong with the gun.
I took the pistol and as I reloaded I said, "That other backstop out there is 100 yards from here. At the bottom is one of last years license plates".
I shot three times, a little over, a little short and the third round hit the license plate.
I said, "No, there's nothing wrong with this gun. Now, let's teach you to shoot".
He came out for some weeks, had fun and was a good student.
One day I told him, "Today is your final exam. At the 100 yard backstop is the other license plate. You must hit it within seven rounds".
He said, No way!
I said sure you can and told him the sight picture he had to hold for that distance.
He a little hit low, a little high and hit the plate with the third round.
I said you have graduated.
He was a very happy man.
