My 32" barreled Guerini 20 ga. arrived yesterday. I took it for a quick test drive, twice around the skeet field at the local fish and game club. Interestingly, the barrels weigh the same as my 32" Beretta SP1 12 ga. (3.25 lbs), even though the SP1 weighs half a pound more (8 lbs.). Somehow, Guerini managed to balance the barrels perfectly and I REALLY like the weigh it handles - it is a bit balance forward, but even shooting unmounted and dealing with some windblown targets, I did not feel any muzzle heaviness or slowness.
I hope to be able to slip down to Addieville in the next couple of weeks to see how it handles SCs, but I can already tell this is a great configuration for non-competitive clays and doves.
