Benelli's new gun, the Legacy 28, may not be as pretty as the model used in its advertising blitz, but it's nonetheless a looker.
According to Benelli, at under five pounds the 28-gauge is the lightest semi-auto in production. Thankfully, it's a true 28-gauge (rather than a 28-gauge barrel mated with a 20-gauge receiver). I imagine it took some tweaking to get Benelli's excellent inertia action to function with 28-gauge loads, but initial testing indicates the Italian engineers pulled it off.
