I've heard arguments that trigger jobs, spring changes, or a multitude of other things that make a gun more "deadly" as far as a prosecutor was concerned.
But back to cocking a handgun, I've never thought I'd be in a situation where I had to cock a handgun in a self defense situation, but I know one non LEO that killed a bad guy after cocking his Walther ppk and shooting the guy in the head. The bad guy was holding a woman at gunpoint. The shooter stated he needed an accurate shot in order not to hit the woman. He probably had a good point. I'm sure that's why the FBI HRT uses (or least used to use) single action handguns.
