I know you like your Beretta Stan, but one that has always worked very well for me in 20 gauge is the XS Sport.

Mine is 30" unported (most of them were ported).

Weighs exactly 7 pounds, and has probably the best overall dynamics I've ever run across.

K-20 has better triggers (which is the only reason for the existence of Krieghoff in my opinion), but scales 3/4 pound heavier than the Browning.

The K-20 handles well, but the Browning XS is better.

They hit the mark with that model, but apparently were not happy with the profit margin. The XS is simply the best of the Citori models, when they can be found without the misguided porting feature.
