For some reason, guys don't like talking to other guys on the range unless there is something cool to look at. If I see something unsafe, then I have no problem pulling someone aside though. Whenever I shoot my SOCOM, it about freaks everyone out on the range. It only takes 3 shots to make everyone stop shooting and look down the firing line.
I have an HK USP 40 with a Surefire X300 and people always look at it and ask "what's that?"
