I played my first games with my pump Mag today. I've played primarily pump for the past 3 years or so, mostly with my S6 or a Phantom. It was a little strange at first having such a short and light pump stroke. It took me a little bit to get into a rhythm but after a game or 2 I was getting used to the timing and the fact that there is no auto trigger. I think with another day of play I'll get the timing down and be able to shoot plenty fast.
Over I'm very happy with how it shoots and how it performed.
