As the title says can it be done? It's just something I have been thinking about for a while and thought I would pose the question.

If it is possible what other parts would be needed besides the barrel? And if so where would you acquire them?

I am beginning to like 357 Sig rather well.

I know a 96FS can with minimal changes. Bar-sto makes an excellent aftermarket barrel.

Slide, barrel, and magazines, I believe.
At least for a 92FS, not 100% on the Centurion. Pretty sure there were kits at one point.

I had a 96 Centurion with a 357SIG barrel by Olympic Arms. No issues, ran fine.

Yes with a complete upper and magazine change, good luck finding one.
