here's my 2 cents worth ,,,, snap up both of the Browning O/U's and see which one you like the best then pedal the other one so you can start saving for the Gamba.

if you say that the owner is letting the Gamba go at a good price, I assume that you will be getting a good deal on the Brownings as well.

I have a Belgian Browning 12 guage O/U (the first gun I ever owned) and I would not trade it for love or money, it is trouble free and a hnadsome,very well made, shotgun.... you would not be sorry with this selection.

I am not a big fan of autos, Belgian made or not, so my suggestion is certainly biased but you know where I am coming from at least

Good Luck with your selection whichever you chose....let us know how you make out
