This picture reminds me of a story one of my college profs. told us. (For the sake of argument this was a long time ago and I don't know my gun lingo with a crap, so some of my facts may be a little off).
When he was working as a Seattle policeman he carried a 45 revlover instead of a 9mm regular issue. He said that he was always getting grief from the other cops because of that huge gun he always carried and how heavy it was. One day there were a bunch of cops being held down by gunfire behind their cars by two guys behind telephone poles. The other cops' guns would hit the poles and riqichet off. He comes on the scene fires two bullets that go through the poles and hits the perps, ending the confrontation. 45's suddenly became more popular in the police force.
