Number One son has his 18th birthday coming up. He's been jonesing for an autoloader. I ordered him a left handed Benelli M-2 back in July which still hasn't come in. I found a Beretta A-400 Extreme (left handed) but chambered for 3 1/2 inch shells. The Benelli M-2 is only a 3" gun. One is inertia driven, the other gas operated. Both in Max 5 camo. Do you shoot one or the other? Do you have a preference. I've been told one cleans a lot easier than the other. Most of his shooting is over decoying birds at 20-30 yards. Unless he went for spring geese, don't know how much he'd need the extra 3 1/2 inch whomp. There is only about a $100 dollar difference between the two guns. Rebate wise, Beretta is offering a camera that goes on the barrel, Benelli is offering $150 dollars in Drake waterfowl gear. I think this is almost like the classic Chevy vs. Ford argument. Looking for some feed back before I proceed with purchase.
