I know, I know a new game is out, but for now MW3 is playing better for me (lag wise). Anyway, I love the P90. Probably my favorite rushing gun as it carries the hefty 50 bullets so you're never screwed when encountering multiple bogeys.
I also like it because to me, it's very simple and easy to use. I would say almost as easy as the MP7, so I always put on rapid fire and a silencer on with it as I find the recoil very little. Anyway, what are your guys' thoughts about the weapon when you used to play MW3, or if you still do?
