I'm not looking to buy immediately but sometime within the next few months. I want an auto loader and I think I've settled on an 1100. I love my 870 so I thought I would stick with Remington. My only concern is that I don't know if I can change the choke tubes in an 1100. I'm looking to buy used unless a great new deal comes across and I was just wondering if there was a certain year or model that came with a fixed choke? I will be using this gun primarily for trap, skeet, and sporting clays.
