I sold my 3 1/2" pump waterfowl gun this spring in favour of a semi, after many trips to as many stores as I could I ended up with a A300, price was great, felt great, adjustable LOP and shims for comb. when I can afford the best of the best I can pass this to my boys. I smashed clays with it all summer and have been smashing ducks now. Not one single issue. I really liked the SX3, but bought a couple flats of ammo with the savings, liked the versa max too, but the A300 felt that much better. My buddy went with the SA-08, which is nice and feels good, requires switching Pistons for light and heavy loads, much cheaper. I say buy the best you can afford, but once cry once, I would have gone A400 if I had the extra $$$. A side note I love shooting ducks with a semi, now that I'm used to not having to pump, I think my target acquisition is faster, resulting in me taking the 3rd shot more often, resulting in more duck sausage in the frying pan!
