My 930 barrel gets pretty toasty.No. To be honest, I have fired the shotgun a lot. Semi auto. Dumping out a lot of rounds in short order.
I have never gotten the barrel hot enough to burn you or hot enough to melt something. Or the handguard.
I have made my own heat shields for silencers though. They certainly can get hot enough to brand you. Shotguns though? I've never seen that happen.
...and use a little furnace cement to seal it up... (jk!) But good idea, Ernst!Was in one of the big box store and in the plumbing section saw this flame protector cloth by Oatey. It's 9 inches by 12 inches and says it will withstand temps to 2500 degrees. Might be a solution for a wrap?
