Sarge made this adorable mockery of the innumerable shooter diagnostic charts circulating on the internet. He takes what we’re all thinking and sums it up in one picture.
YouTube videos and gun forums are dubious sources of knowledge at best, and they provide no real-time feedback for the shooter. A simplistic chart (which is designed to correct defects in long-distance, one-handed shooting, by the way) might help as part of a whole suite of training tools, but taken by itself, it is of little value.
Most people don’t need a more expensive gun, a laser, or larger magazines. They need to find a shooting coach and drill on fundamentals. Once they do, they find that shooting is an enjoyable hobby rather than a disappointing ordeal.
