I have a Rizzini B small gauge multi set gun and really like the longer barrels. If 32" were available I'd have gotten them. For me, the scaled frame 28 ga was too light for targets and I went with the 20 ga frame. Which allowed me to get 20 ga barrels too. Two sets of 20 ga actually; some whippy 28"-solid rib-fixed choke and a 30"-vent rib-sporting, 29"-solid rib-28 ga, and 30"-410-vent rib-sporting. Piggy, no?
Perazzi's a better gun, all-round.
And functionally better for high volume shooting; when reloading the Rizzini has to be pushed open the final bit, against very light spring pressure. The gun has never failed to eject so it doesn't affect opening.(Something to do with their design of the extractor mechanism, which is entirely in reciever. The forend only has a cocking bar) Minor, but not something to deal with 600 times a day.
