Does anyone out there own or have any experience with the Ruger Blackhawk supplied with interchangeble cylinders chambered in 9mm and .357 magnum? I am curious as to how a single action pistol accomodates an rimless 9mm cartridge give that moon clips cannot be used. I would also like some feedback as to accuracy in the 9mm configuration. The reason for asking is twofold. My primary pistol is a 9mm and I have an adequate stock of ammo for use at the range. It would be easier to take one caliber to the range for practice and 9mm is a little cheaper than .357 oe .38 special. Secondly, I have always had a desire to own a single action in .357 and perhaps back it up with a lever action rifle in the same caliber down the road a bit. A revolver like the Ruger would make life a little easier. It is not intended for home defense, just to satisfy the joy of shooting. Any feed back would be greatly appreciated. Thanks!
