If its a Browning Gold shotgun(autoloader) with a gold trigger (which doesnt mean anything on those guns)Its a dern fine shotgun for ducks. If its a Browning BPS (pump) which can also have a gold trigger (still doesnt mean anything just pretty) Its a great gun too. The Browning A-5's are another story altogether (the gold trigger means something on these guns,ie: standard or light) The Remington 870will be cheaper but its a good gun too. But remember you get what you pay for. the Brownings will have a better fit and finish usually.The 12ga has by far the most options at loads. Make sure any gun you get has at least a 3" chamber and is rated for steel. (Any modern gun with screw in choke tubes will be rated for steel shot.) Any more ?'s (ingeneral or about any of these guns) or if you want some more info about your buddy's gun either post some pics or get a better description and we'll try to help you out!
