It was the best SMG in cod 4 but in MW3 is doesn't appeal to me much since the PP90 and MP7 have taken over. In MW2 it was all about the UMP45 with its good accuracy and damage now in MW3 its not as used much because there are better choices to choose from now. The MP5 is still a good gun to rush with but the problem is you face tough competition against the other SMG that are more effective at close quaters.
