Ruger has and still does make some Black Hawk's with interchangable cylinder's. However they are FACTORY MADE.

Ruger's are NOT MADE for their cylinder's to be interchangable form one revolver to the next. IF you do this you are asking for real trouble.

Ignore anyone who tells you differently!!!

If you want an additional cylider the revolver must be sent back to the factory. I am not talking about the BP revolver's. Tom.
