I am on my third season of shooting my 935 and I love this gun. I like to shoot 3.5" shells myself. But that's just so that when I miss, I know I did everything I could!
Last year, I was walking through the lake to my blind in the dark. I dropped my gun in the lake and when I pulled it up, it was filled with water, mud and all sorts of gunk. I cleaned it out the best I could with lake water and hunted anyways. It shot flawlessly all day long. I think I put almost two boxes of ammo through it that day. That oughtta tell you how often I miss! The gun is great though. It's super simple. I highly recommend it.
