The PPK
does hit like a brick through a plate glass window, when you throw it through a plate glass window!
Don't blame the movie for that line, its right from the book. Ian Fleming didn't know much about guns. Or holsters either, for that matter. The Berns Martin holster that Bond wears must have been custom made for Her Majesty's Secret Service, because at the time Berns Martin didn't catalogue a single holster for an auto pistol. (or so I've read
)
There are tons of great gun lines in different movies, some funny, some dramatic, and some so badly inaccurate they make me wince.
Sound effects aren't any better. EVERY empty gun I've seen in the movies in recent decades signifies it is empty by going "click, click, click...
Doesn't matter what the gun is, doesn't matter if the slide is locked back, or not, doesn't matter if the gun is even physically capable of going "click" just once, they all go "click, click, click" when empty, usually followed by the shooter throwing the pistol at bad guy/monster/ superhero/ etc...
And why does Superman stand there getting shot, but ducks when the gun is thrown at him? (old tv series)
