Yesterday and it would not quite fit. It would only go in about half way.
I studied it and measured but did not want to start filing on it and contacted Wes. He very readily agreed to send me another and offered to refund my money if I wanted it.
Today I decided to study it again and discovered the problem was probably the diameter of the bushing barrel in the "grooves", which receive the 500s "lands". It miked out to about .002 more in diameter.
After about 20 minutes of careful filing with small files the "Non" compensator went in and can be removed with finger pressure.
I immediately took it out and put some light and heavy loads through it and to say it is a pleasure to shoot is an understatement.
My hearty thanks go out to Wes and his effort in making my 500 a much better toy!!!
