you'd have to check weapon.dat, it has the fire rates in there, and all other weapon stats. pretty sure how many shots are fired as based on animation speeds (I just checked actually, and yes). so, it will be very depending on your FPS as to how quickly it will shoot, and there would be no definitive fire rate per minute.

have a look here, maybe it can help you: http://www.gtamodding.com/index.php?title=Weapon.dat

if you were going to use a timer for something to detect something with fire speeds of people's game, I wouldn't. sounds like a huge problem to me especially with pausing.
