I am looking at buying a new field gun. It will be used primarily for dove and waterfowl hunting. I have been leaning toward the Beretta Extrema which runs about $1,000 new, but the 390 can be had for just over $500 at Walmart. The upside to the Extrema is the 3 1/2 inch chamber vs. 3" for the 390 which only be a factor for goose loads. Any experiences with either gun would be appreciated. Thanks in advance.
