I was very satisfied with my SX3 for the first 10,000 rounds. Things went downhill quickly after that. I ended up sending it back two times and the last time I had major problems with it I just bought the parts and repaired it myself instead of waiting 12 to 16 weeks to get my gun fixed. I had problems with the bolt and magazine twice and I've had problems with the breach and trigger group. The dura touch is anything but durable. It looks and feels good when new but after a year in a duck blind it's quite embarrassing.
All I can say for Remington is they are heavier than most. I only own two Remington shotguns and they are pumps so.....
Here are a few pictures of my SX3. This is from wear and tear not abuse. There is a reason why Benelli and Beretta can charge $600 more for a gun and they still sell the heck out of them. I haven't shot this gun in over two years now. It's been one of my biggest disappointments in firearms in a long time.
