It was a good question when you posted it, and still is. Probably not too many folks have tried out interchangeability. I certainly can't spot anything in photos to suggest the sights are any different, but the collar is under the wood in those images, so I can't say. You need someone who owns copies of both and who is willing to take them out of their stocks to look. The main thing will be the barrel diameter in front of the first step in it. If that's the same, I guess they should interchange.
