Any opinion if the supernova is worth the extra money over the nova? thanks
I honestly believe so (I own a Benelli Supernova Tactical).
The main benefit of the Supernova is that it [should] come with a pre-tapped/drilled receiver for various mounts and allows for different stocks to be used (namely the Comfortech and Steadygrip stocks; also there is a collapsible stock available, if you can find one and/or afford it). The Nova, however, does not have either of these features and therefore is somewhat lacking in configuration ability.
Plus, I do believe the QC for the Supernova is a bit higher vs the Nova.
Nothing wrong with a Nova....I just prefer the Supernova myself.
One word of warning, however. The barrels for these things are ridiculously expensive; almost to the point where, should you ever want/need one, you would be better off just buying a second gun. This is why I personally have decided to no longer buy Benelli pump shotguns (brand new ones, at least). But, given that the barrels on these guns are very solid and feature a quality, chrome lined bore...the need for replacing one should not come around that often, if ever.
Still something to think about.
Regardless, the Supernova is a fine shotgun and I am proud to own one as I certainly do not feel as if I "lost" all that much in buying the gun. To expand on this; IMHO, it would be quite difficult to find a shotgun (within the Supernova price range) that offers equivalent features, quality, and attention to detail.
Now is it the best value, over the long haul? This is for the buyer to decide. Either way, the quality is certainly there.
If you do get one, I think you will enjoy it. I have...
Good luck!
