I'm not sure if you own a Nova H2O or not, but evenwithout the SNT features you mentioned, it is a nice gun. The SNT's largertrigger guard would be nice with gloves.
I do believe that owning an H2O of any stripe solely for home defense defeatsthe purpose of it being built as an outdoor/corrosion resistant weapon. Aregular SNT fulfills the HD purpose nicely... and unless your home is under a waterfall, I wouldn't give a second thought to the SNT's corrosion resistance in the HD role.
With this in mind, I'm not a gun collector either (they're just tools, afterall), so I wouldn't be interested in having one for the sake of having one.
In my mind, the Nova H2O is the ideal bear defense gun; a poor man's AlaskanCo-Pilot, if you will. If Benelli did start offering a SNT H2O, I'd buy one toreplace my standard Nova H2O, but only because a collapsible stock would reducethe overall length of the weapon.
As it stands, though - even with its standard stock length, the Nova H2O scabbards in an Eberlestock pack very easily.
Take care.
