Docs comment on cleaning reminded me. If you are going to shoot a SuperX1 more than a little then a stainless steel magazine tube would be a wise investment.
The Super X short stroke gas system ( as good as it is) does create more moisture on the mag tube than the Remington 1100 gas system. All mine Super X'do have the stainless mag tubes.
The Beretta 300/390/391 mag tubes are annodized aluminum and don't have the corrosion issues.
I DO NOT SHOOT ANY OF MY AUTO SHOTGUNS "DRY", a coating of Breakfree on the mag tube prevents carbon build-up and they run longer in-between cleanings. I also use axle grease on the action bars and and other parts showing blue wear ( where the blue is being worn off in the auto cycling process over time).
The Remington's show more gun blue wear than the Winchester Super X and almost none on the Beretta 390's.
