Thought I'd share, I picked this one up a year ago for cheap ($175); it's a pre-prefix 3-Screw 357 Blackhawk that's not made it back to the factory yet:
The right side photo shows the 9mm cylinder that came to me with the gun, but I don't think it was originally sold with the Blackhawk. Maybe, dunno for certain the way the old guy talked. Sounded as if he had another 357 Blackhawk Convertible he sold without the 9mm cylinder; he had forgotten about it. In any event the 9mm cylinder functions as if made for the revolver, though.
