FFP takes a little getting use to if you're use to the reticle staying the same size. However, after you've used a FFP for a while you'll never want to go back.

Don't discount the Benelli M1. Its built sturdier than the M2, and uses the same inertia system. I bought my first Benelli M1 Super 90 in 1994 and still have one I bought in 1996. Over the span of that time I've owned quite a few M1, M2 and M3. I don't care for the M3. The "pump" location is too far out for a non orangutang. The M2 is just a cheaper-to-manufacturer M1.
