On Saturday, I spent some time at the pistol range.
It was somewhat relaxing. Though partway through, I noticed that my hands shook slightly as I took aim. Not tension or worry: it's a kind of physical exertion that I don't do very often.
I set the target at 21 feet. Then I began shooting. I tried to hit a pace that wasn't too fast, but didn't dawdle: fire, breathe, aim; fire, breathe, aim.
Even with that, I felt like I was rushing. I had a scattering of shots to the lower-right on my target.
Something like 40% of my shots (even with slightly-shaky hands) ended up within the 10-ring on on the target. Another 30% or so were inside the 9-ring.
This feels low to me. Not dangerously low: all of the 70% would be considered good shots in a self-defense situation. (Assuming the assailant stood still long enough for me to shoot more than once...)
A distance of 21 feet is dangerously close in one regard. However, it is a challenging range to shoot a pistol at. Most of the other people at the range were working at 15 feet or less.
One man, a much more patient shooter than I, taped a playing-card to his target at a distance of 15 feet. Then he tried to shoot out the "Ace of hearts". One carefully-aimed shot at a time.
I took away two lessons. One: I need more time practicing hold-and-pull-trigger on my carry pistol. Two: I need to aim carefully. Speed can be accomplished after accuracy.
