I watch movies with my iPad in hand to check out authenticity of history or logic.
Searched to find the riles use the Tom Berringer film, "Sniper "

From that found this link that espouses common ways movies illogical gun uses.

After the authors take, there are hundreds , maybe, of comments of other common mistakes.

My all time old fav is the 50's Superman where in the bad guy shoots bullets at supermans chest, wher he just stands there with handson hips. then when the gun is empty, the bad guy throws the gun at superman. What does superman do? He ducks.

(Also, this is about goofs in movies relating to gun use. Not about gun control. Take that discussion to the Soapbox)
