I hear what you are saying K4DV the characteristics of the recoil from a Benelli are different to a gas gun such as a Beretta.
For a given load the recoil is identical in energy, this being the equal and opposite reaction to the pellets exiting in the other direction. The inertia system however delivers the "reaction" more abruptly compared to the gas cycling systems but the energy involved is the same - you can't destroy energy.
I shoot a L/H M2 and I gave it to a friend to try last weekend, he shoots R/H. He put about 10 shells through and gave me it back saying it was the most recoil he has ever felt. He has shot my O/U and my 1910 Westley-Richards S/S in the past. I don't think it is that bad but the L/H stock is set up for me. Which is why I said gun fitting does make a difference.
Most guns you can shoot straight out of the box, even if they don't fit you and they'll be OK, the Benelli semi-auto isn't one of them.

P.S. Only $1,000 ?? My M2 cost me £850 and at nearly $2=£1 that's about $1,700 !!
