How rare is the 9mm S&W 5906 Super? I've been looking for one for awhile and put a WTB ad on the forum but I haven't come across one yet. I also read that someone just made the uppers that fit on a 5906 frame, are there any of those around? If you can help me out please let me know. Thanks.

This thread should have everything you need to know about the Super 9:

5906 "Super 9" Information

They are extremely rare, only 40 of the single barrel versions were made and somewhere between 250-660 of the three barrel versions were made, but most of those three barrel versions were exported outside the US.

Thank you for the link. I doubt I could afford the 3 barrel version, I would just like the single barrel 9mm version.
