There should be a button on the back of the controller
You can modify your playstation 3 controller to press a specified button at high rates of speed. In a first person shooter, this causes rapid fire. Directions for this can be found here, http://consoleupdates.com/2008/07/12/rapid-fire-ps3-controller-mod/

Yes like the m16 it would be rapid fire and the type95 (mw3) would be full auto(rapid fire).
