While I have and use several very nice classic SxS's, one area that we hunt requires non-toxic shot. In that area, I use regular steel shot in the right (Open) barrel, but have to use hard-t0-find $3 bismuth shells in the tight left barrel.
The new CZ came with 5 choke tubes,is "steel-safe", and I won't be upset if it acquires a few scratches.
First day out I shot to roosters with 3 shells. That may be the first time I went hunting with a brand new gun, without first test-firing it beforehand. It worked fine.
