Okay so I actually found a .44 cylinder. I've got one on the way. I held out long enough, though it was hard lol.....but I waited just enough and found one.
So, as you mentioned, indexing with each trigger pull. I was worrying about the dimensions of the details and how well they match up on the ejector of the charter and tomen. If the hand would work at spinning the charter cylinder with each pull. Seen any examples of simply putting the charter cylinder in and it working with the tomen hand and stop? I was only considering replacing those parts if the tomen parts wouldn't work with the charter cylinder.
