Hi all I'm looking at a mossberg 930 18" with the breacher on the barrel. Would this be a good option for 3 gun? I would add a +2 or 3 for better capacity. Or should I go with the waterfowl version with the 28 inch barrel and have it cut down 24 and threaded? Anyone that can help it would be much appreciated I'd like to buy once and not have to upgrade later if I get more serious about competing. Also I know an FN or a Benelli would be great but I am on a budget, thanks in advance.
