What do we see in our movies?
Today it's Glocks, M9s, and 1911s. Also occasionally a snub nose airweight or similar.
But if you look at just about any movie set from the 40's on, the 1911 is probably featured somewhere in a gun movie. Gangsters, doughboys, vietnam vets, gangsters (modern day), cops (somehow), average joes gone renegade, that odd movie with Angelina Jolie where they bent the bullets.
I'd say these are THE guns. If you see it in a movie, on a poster, no guns sign, whatever, it's one of these. It's odd that in these roles the 1911 seems to be sexy where as the M9 is played up to be sneaky. It's either criminals or assassins using it and many times with a suppressor.
