I understand.
It's a very good gun.
I managed to find an unported 20 gauge XS Sport when they were making them, and it has been durable and reliable. It may be the best handling shotgun I've ever used.
Even in 20 gauge, they are so sold on the idea of porting that only about 30% of the XS Sport models were delivered without porting.
I have two ported guns for the same reason as you are dealing with, they simply don't make a non-port version.
It's not difficult to deal with, but I'd sure rather they were not ported!
