Well, I have $400 in the gun, $10 in the barrel band. Waiting for my smith to get the new barrel crowning tool for .45. Once he has it, the band goes on and we fit the sight. Going to take it from 5 1/2" to about 4, 4 1/2 or 5. I don't know for sure yet, going to take it down 1/2" at a time to see what looks best.
