I've had one for a year. I was looking for a dependable waterfowl auto and it was between the V3 and the SX3 and the V3 fit me better so I bought it. I really like it, the only complants are shooting trap with light loads I will occasionally get some powder in the eye since the ports are right in front of the receiver and the other is that the front bead broke off somehow while duck hunting. Also watch the front of the shell carrier, mine was a little sharp when putting shells in the tube. It shoots straight, patterns well, feels good, and hasn't malfunctioned. Recoil isn't bad either except with the Hypersonic.
I don't use it for predator hunting, but it throws great patterns with Black Cloud 4 shot and BB at 50 yards with the factory IC and Mod chokes.
It does only come in 26" or 28". I have the 28" and kind of wish I would have got the 26" just because I'm used to a shorter barrel. I bought mine for $720. So far I would buy it again no questions asked. I have had 4 Benelli's and still have 3 so I know they are built well and easy to clean but can jam like everything else.
