Deagle has a RoF of 200/min.
I got myself some clocks and found that the Deagle shoots a bit LESS THAN 2 SHOTS PER SECOND.
But even if you count it as 2 shots per second it makes up to 120 rounds / minute.
The Deagle obviosly doesn't shoot 3+ shots a second, does it?
Edit: SORRY DC! Anyway I did some more research and found that the Deagle does EXACTLY 100 shots/minute! That's exactly 2 times less than stated in the tooltip.
