I'm on the fence, and I have no idea which gun to buy. A few days ago I was 100% on the Urika 2, now the M2 is beginning to catch my eye. I have called all over the Houston area to try to find a place to shoot these guns side by side, but nobody does that anymore.
So, I'm going to have to go by word of mouth. Who has shot these guns and which gun would you go with? I'd like whoever is responding to site specific reasons, not just one is better than the other. Why is better.
First off, there is no real comparison in my mind - the U2 is a gas job, and the M2 is the infamous Inertia system.
I'm real-real close to closing a deal on either a new SBE II, or the M2, and for reasons that are really really important to me. I owned the Benelli SuperSport (same basic platform as the M2), and like a fool, I sold it. Although I've never shot or dismantaled a U2, I do have a gas job (Franchi Raptor 712).
The issue for me was cleaning, really. Gas jobs are Ok for economy, and situations where you don't shoot a lot, but once I tore down my Inertia driven Benelli SuperSport for the first time (when I still had it), I was totally sold. Bada-bing!.
Over and above the cleaning issue, I didn't like the idea of hot powder gases being trapped under the forearm piece. It looks like the U2 might have a vent at the tip of the forearm, but still, gas operated guns in my opinion are a "compromise design", period. They can't be equated to the totally clean, and inovative design idea of "inertia". Gas ports and parts will get dirty, carbon up, and quit working. Newton's law
on the other hand will never fail.
In my mind, if you are even so much as "remotely" comparing a gas job against an M2 (with ComforTech!), you've already made your decision - get the M2. I am of the belief (maybe incorrectly), that the only reason someone would not choose a Benelli Inertia driven gun when there is a "choice" to be made would be money. But, as you said, the very fact that you are considering it means that you can afford it.
So the specific reasons for the M2 (or any of the Inertia Driven systems w/ ComforTech) are as follows:
1) Reliability, reliability, reliability. There are only like 12 moving parts in the entire gun!
2) Clean!. Shoot that gun (even in the rain) till the cows come home, and the cleanup (if any) is next to nil.
3) Complete tear-down in "stupid" easy to do.
4) Choice of 3 different gel-filled recoil pads, and comb pads available.
5) The ComforTech stuff really works.
I'm missing my SuperSport big time (thus why considering the M2). I was really really down on the whole marketing hype of the ConforTech deal, but after my 19-round Estate fume-fest experiment, I quickly gained a new respect that that system.
