I have to say it! The PM-9 kicks a**! If you use it like a shotgun, you will do ridiculously good with it. My current KD with just this weapon is a 2.77 with my last 3 games had me going 27-6, 16,3, and 10-4 while still playing the objective.
Love the PM-9, and playing objectives. glad I'm not the only one
This is how I use mine, what do you like to use on yours?
