Right.

And

Now that I think of it, there is no reason to believe that since my Pietta cylinder works in my FIE revolver, that any Pietta cylinder will work in any matching FIE revolver.

The FIE I have is not a bad revolver. I don't shoot it much but it is alright. I don't own anything marked PR.

I don't think we have ever pinned down who manufactured for FIE. It may be that several different builders made pistols for them over time.

Well....anyway, my FIE accepts my Pietta cylinder.
