SuperNova or 590A1 !!
590A1 is going to be big and heavy. That's a 20" with a heavy barrel and extras like the bayonet lug. There is an 18" without the bayonet lug, IIRC. A Supernova's going to be a lot lighter. Parts can be expensive though. If you want a Benelli barrel, that's $350 which is the cost of a complete Nova. If you don't need the pistol grip stock then you might consider a Nova instead.
Also with the Ithaca Model 37, the barrel on the new Defender model is fixed meaning you can swap barrels.
