If I was getting a semi-auto shotty the only two I would consider would be a Benelli M4 or FN SLP
No offense, but spoken like someone who knows nothing about how 99% of all shotguns are used. You are recommending two tactical type guns for a guy who wants to shoot clays and hunt birds. Are you nuts?
The only people I've ever met who use the term Shotty, consider a good day of shotgun shooting to be blowing up milk jugs and shooting at shipping pallets.
JeffC - first question, do you intend to do any waterfouling? Do you want a 3.5" chamber gun?
How important is weight to you? If you are hunting, you do more walking than shooting. A light gun is better for hunting.
If you are shooting clays, you do more shooting than walking. A heavy gun works better for targets.
These are a couple of items to weigh against each other. I don't know the weight of these guns, but you may want to look them up.
One thing that nobody mentioned to you is fit. Shooting a shotgun is an inherently more instinctive thing than shooting a rifle or handgun. Because of this fit is more important. Your eye IS the rear sight. Your eye needs to align in the right place every time. If all your data tells you the benelli is the gun for you and the first time you pick up the versa max, its just right for you, then you should get the versa max.
Thats the way it was when I got my Benelli SBE II. I borrowed a friends and the first time I brought it to my shoulder, I knew I had to have one. It was the most lively big auto I had ever handled. It felt pounds lighter than my 1100, even though the scale showed the difference to be only a few ounces. Part of it was the 24" bbl, which kept the length of the gun reasonable with its long receiver. .
My buddy tried the Benelli, Beretta and the Winchester/Browning. He liked the Winchester by far. It just "came up" better for him. He ended up buying the same gun with a browning label because he found a deal on it.
