The law of guns in movies

[Yournamehere]

A. That is circumstatial to you, and possibly others, but doesn't reflect the gun as a whole, with everyone, and certainly not a majority of people.
B. Same as A2, but I'll add that I slingshot as well and I have never activated a slide mounted safety in practice or even come close to doing so on my Beretta or my S&W 5906.
C. It is in fact bigger than most other 9mms, but that is based in relativity and isn't necessarily a flaw, and most certainly not a flaw in the design.
