I was at the local gunshop this evening and a guy asked them if they had the new Taurus revolver that shot .357 and 9mm?! I almost dropped the Remington 870 I was looking at and the counter guy was like .. "ummm ... never heard of it" Is there any truth to this? If so, I would love a link to it.

Edit: Wrong wording in the title. Chamber is the wrong word I believe. I think I was looking for cylinder. What I meant was, the guy asking about it made it sound like you could change out the cylinder itself for either .357 or 9mm. He said it was new. I don't have a clue.

I think you misunderstand. 9mm can be chambered in a .357, if moonclips are used. 9mm=.36, IIRC, while .357=.357 for the bullet diameters. .38 Special=.36 as well, which is why you can use .38 out of .357 bore. Plenty of firearms have been made like this; Ruger has an offering with two different cylinders (one for 9mm, one for .357--moonclips take up more space in between the cylinder and face of the frame than do rimmed rounds), and there was this thing called the Medusa which fired all 9mm wide rounds--.357, 9mm, .38 special, 9x18, 9x19, 9x17 (.380).

Only revolver I know of that had "two chambers" was the LeMat, and some other crazy french design that held 20 rounds.
 
Actually, you can not chamber a 9mm in a .357 because the case head on a 9mm is too big. You can get a cylinder reamed out to take a 9mm with moon clips, and it wills still fire .357, but the cases will bulge.
 
Unless Taurus is still making 9mm cylinders (or has some left over) from their discontinued line of 9mm revolvers and is shipping some .357's with two cylinders, cranes, etc. Wishful thinking maybe, but I'd buy a rig like that in a heartbeat. Especially in their copy of the S&W centennial type guns.

The 9mm case head isn't the problem - it's the fact that 9mm is rimless and most revolvers headspace on the case rim. The moon clip provides a rim for the case to headspace on, and for the ejector star to engage & get the empties out.

The dual cylider Rugers are the single action Blackhawks. Because it's a seperate cylinder, and since SA revolvers use ejector rods that contact the inside of the case head, moonclips are not needed. For those reasons the SA cylinders are bored for the auto cartridges to headspace on the case mouth (as they woul in an auto pistol). The Blackhawk convertibles are available from the factory in 45 Colt with 45 ACP cylinder, and 38/357 with 9mm cylinder.
 
Try sliding a 9mm cartridge into a .357 - it will not fit past about half way.
