4506 slide on 4566 Frame?

[TiberiusBombard]

I recently purchased a S&W 4566 and was offered a 4506 slide from a friend who recently bought a brand new one. I'm wondering if the 4566 frame would accept the 4506 slide for two interchangeable barrel lengths.

The 4506 and the 4566 use the same frame. You can interchange uppers, as long as both are pre-TSW or TSW.
