I've got a M1S90 w/ ghost ring sights that you can play with if you like. It will run the cheap bulk pack stuff from wal-mart, but GJM is right... the thing kicks like a mule.

The gun you're considering can be "ghost loaded" with an extra round... the newer benelli m1/m2 cant unless you modify the bolt.

Also another thing to consider is the LOP. If you want to shorten the factory stock it is a PITA, but can be done. I think mesa tactical came out with something aftermarket but I haven't ever handled one of their stocks.
