I wonder how it works with shot trying to go in all directions through the suppressor. I can understand a single bullet from a rifled barrel will go straight through but it seems that shot would damage the internals, as the pattern tries to spread.

The shot is contained within a cup in the shotgun shell. Instead of wide-open baffles, a shotgun suppressor has a smooth tube keeping the cup intact, with lots of tapered holes for bleeding propellant gasses off before the cup exits.
