Will replacing a revolver cylinder throw it out of time? Is this something that needs to be done by a gunsmith? A little background: I am looking to send my 442 cylinder off to have a 9mm conversion done on it. I want to have an extra cylinder to shoot .38s if I still want to, but I am not sure if I can simply buy a second cylinder or if I would have to have it fitted by a gunsmith.
Thanks in advance.
