Stoeger Coach Guns and Slugs?

[Mikofox]

I've seen the question around, but not the answer.

Can one shoot slugs (preferable my favorite Barnes X Sabot) with these guns?
I'd like to have one barrel for buckshot and the other for slugs, or both capable for slugs, but I don't see that these guns have an option for rifled or smooth cylinder bore choke inserts.

Or if no choke inserts are available could a gunsmith modify some other brand insert for these guns. I don't know if this is possible or even if there is any kind of standard for choke inserts.

Stoeger does have a cyllinder choke available, I'm not sure about a rifled tube though. I heard on here once that the Stoeger tubes interchange with Winchoke, Browning Invector, Mossberg Accu-choke etc, maybe some one can confirm that. Rifled tubes are available for that thread pattern. You can use foster or Brenneke type slugs through any choke though if you can't find a cyllinder or rifled tube.
