Funny scene and line

***Spoiler****

I enjoyed this film a lot. Cagney is just so good.
I particularly liked the FBI training scenes. Especially the shooting range with Cagney and Armstrong.
Armstrong's character, McCord, was showing Cagney's character, Davis, how to fire the gun and was saying how the noise may be frightening at first and it takes some getting use to.
And of course Davis knew exactly how to handle a gun and shoot and he aimed at the target perfectly. And I just loved it when he handed the gun to McCord and said...

"Would you mind reloading this. I get a bit frightened"

Funny and perfect delivery.
