F&N/Win 1300 and surefire?

My question is very simple, will surefire weponlight fit on an F&N Police Pump?

They say it needs a "long magazine tube" meaning 7 rounds?

If you don't get a response here, drop Surefire a note. In my experience, they are really quite quick to respond and forthcoming when something isn't going to work.
