I recently shot my qualification course for my PD recently with my little 637 Airweight. Afterward, I called my friend Joe Speer and thanked him for the good work that he had done on the trigger, and bobbing the hammer with serrations over the back of the bob. Frankly, for 50 rounds, I shot like I really knew what I was doing. I was a rock star, even though I was shooting the entire course with 158g +P loads out of a 15 oz revolver.
I could use some work on my reloads, though. If I'm only acceptable with reloads on the range, how well do I expect to be in an incident where the balloon goes up?
The single most realistic movie depiction of a revolver reload when the adrenaline is pumping is in The Silence Of The Lambs, in this scene here. Keep in mind that (temporary) Agent Starling has just gone through extensive training, and is at 27 years old probably in the best shape of her life, but she can barely get that M13 reloaded, for all the involuntary shaking.
Sure, we're seeing an actor portray it. But I've had fight-or-flight adrenaline flowing through my veins before, and my motor coordination was about like that, too. Reloading a magazine is a darned sight easier under that kind of stress.
