I thought a useful thread would be, "what do you do to keep in shape for that SHTF event?". I think a fair number of CHL holders think they've arrived when they get the license, and may not keep training. I'll go first.
I have several guns, and rotate my practice with them, so the carry gun only gets fired every few weeks (it's not that much fun to shoot). However, I try to do this periodically:
I warm up with shooting at a bullseye at 7-10 yards. Then I put a B-27 FBI target out at 7 yards, load my gun, rack it, and lay it on the bench. It should be in the same condition you would carry it, i.e., cocked-and-locked, safety on if you want, not racked if you want, whatever. On my signal (not having an assistant), I grab the gun and see how fast I can put 2 shots on the target, using only a flash picture. The goal is 3 seconds. If you have to do anything besides pull the trigger, it will take a little longer. With the gun not in my hand, I'm trying to simulate a desperate emergency. Repeat as necessary. The location on the target matters, just as it would in real life.
Most ranges don't allow drawing from a holster, which would be a better simulation, but this is a good exercise. Unless you practice emergency shooting, you will be surprised how awkward this feels, and how less than stellar the results.
As the Boy Scouts say, "Be Prepared!".
