Ruger Blackhawk?

D@D
I've seen some of the convertible Ruger Blackhawk revolver (9mm/357mag), my question is can you put a 9mm cylinder in any Ruger Blackhawk 357mag?

    A few years ago I was looking at a Blackhawk revolver and it had a stainless back strap and shell ejector, I have been looking for another of the same now and cannot find one. What model was this revolver?

    Two issues to consider:
    First, Old Model .357 or New Model? The Old Models featured a smaller frame and cylinder. With the introduction of the "first" new models, the larger .44 frame was used for both .44 and .357. (Until the most recent return to the smaller frame for .357's.
    Assuming compatibility here, the question becomes whether or not special fitting is required. I've had several .22 L.R. and .22 Mag. cylinders drop in with no problem. The higher pressures of the 9mm and .357 could be a new ball game. I'd probably try it, but wouldn't recommend that someone else do the same.
    That said, if the cylinder will fit in the frame, has minimal end shake, locks up tight, and aligns all 6 chambers properly, then you should be o.k.

    9mm luger and .357 operate at similar operating pressures, 35,000 PSI for each. 9mm luger bullets are nominally .356 of an inch in caliber, but in practice, lots of the manufacturer's 9mm luger barrels are .357.

    So in terms of simple operating pressure you should be OK here.

    I can't speak to availability of 9mm luger cylinders for the gun you want to try this in, but if you can find one that fits, it would probably work.

    All the ones I have tried work just fine. The frame and cyllinder of the Ruger can easily handle the 9mm. They actually are very mild in this gun.

    I have one that came from the factory as a stainless 357. I sent the gun back to ruger and had them fit a 9mm barrel to it (they don't make the 357/9mm convertible in stainless).
    they set it all up and even stamped the cylinder to match the gun.
    problem: it cost $300 two yrs ago.
    you might want to contact ruger and see what they charge for a 9mm cylinder.
