No one ever gets shot in the shin.

I do believe you're referring to Judge Dredd's Lawgiver II. :D

Getting shot in the arm, leg and shoulder are not serious wounds

2 men + 2 shotguns = 3 rounds total. Anyone remember the movie that's from?

I forgot actually, but I know what you are talking about. Christan Slater is in that.

Also in movies, most of the time, the main characters wouldn't pick up guns dropped by enemies even when it's safer to take the AK or Uzi than keeping their pistols. Except for the movie The Kingdom, that ending battle had them all using guns they've picked up

the femoral artery will bleed out just as quick as the jungular, the shoulder has a lot of small bones and nerves and will take a while to heal. Also, people dont get hit by a bullet, stop all forward motion, and go down like a rock isnstantly. The human body can hold in there a while. Especially with adrenaline blocking out pain.

I think most of us know that. That's the point, in gun movies, none of that ever happens to the human body

Rule:

Main character will do a raid with just a pistol and sometimes body armor worn over clothes, while the rest of their team wears tacgear, mp5s, m4s, etc.

Too many shows to count, 24, numb3rs, etc are the violators i can think of right now

When in full gear, a main character would take off his helmet and that would be the signal for "it's on now."

The best way to fire a pistol is to hold it sideways,or upside down,than spray and pray.
Handguns always make the cocking sound whenever they are drawn or pointed at someone.This is most amusing when it's done with a Glock or other hammerless weapons.
After firing about 400 rounds from an SMG or an assault rifle(from a single magazine of course), the next time they are aimed at the main villain/hero it will make a loud click sound,preferably multiple times(this does not count for DA/DAO handguns :()
