One of my favorite sci-fi movies of all time is Terminator 2, although it is riddled with gun mistakes... you just have to try to overlook them and enjoy the action. The machine never seems to carry his 1911 in condition 1 because racking the slide is good for dramatic effect, I guess...

My favorite is the scene where the 2 terminators meet in the back halls of the shopping mall... Robert Patrick has a Beretta 92FS and shoot something like 22 shots rapid fire... I guess that is 15 + 7 in the pipe... LOL
